Struct Manager 

pub struct Manager<B: HelmBackend> { /* private fields */ }

Ported from Manager in manager.go.

Implementations

impl<B: HelmBackend> Manager<B>

pub fn new(backend: B) -> Self

Ported from NewManager. The Go original panics if backend is nil; a Rust B: HelmBackend is never null, so that check has no equivalent here.

pub fn deployer_type(&self) -> &'static str

Ported from Type.

impl<B: HelmBackend> Manager<B>

pub fn build_dynamic_overrides( &self, deployer_config: &DeployerConfig, caproni_config: &CaproniConfig, ) -> Result<Option<Value>, HelmError>

Ported from buildDynamicOverrides. Merges every configured dynamic override into a single tree of Helm values. Later overrides win over earlier ones. Returns None when no override contributes a value.

ctx (Go’s context.Context, used there only to scope a slog.DebugContext log line) has no parameter here; see PORT_NOTES.md’s note on this crate’s explicit-dependency-injection convention for context-carried values that this session’s ported submodules do not otherwise need.

Errors

Returns an error if an override names an unknown or not-yet-supported type, or if resolving one fails (an unreadable file, an invalid Helm key path, or a conflicting key path).

Panics

Panics if deployer_config.helm is None; callers are expected to have already checked deployer_config.deployer_type == "helm" (ported from Manager::Validate/Deploy’s own type check, not yet wired up here – see PORT_NOTES.md).

impl<B: HelmBackend> Manager<B>

pub fn deploy( &self, deployer_config: &DeployerConfig, cfg: &Container, ) -> Result<(), HelmError>

Ported from Deploy. Deploys the Helm chart, upgrading it if already deployed.

Errors

Returns an error if deployer_config is not a helm deployer, preparing the chart source fails, building the values arguments fails, or the underlying helm install/helm upgrade call fails.

Panics

Panics if deployer_config.helm is None; callers are expected to have already checked deployer_config.deployer_type == "helm" (this method’s own first check).

pub fn status( &self, deployer_config: &DeployerConfig, _caproni_config: &CaproniConfig, ) -> Result<Status, HelmError>

Ported from Status. helm list failing (missing namespace, helm unavailable, …) is treated as “not deployed” for idempotency, matching the Go original’s //nolint:nilerr comment – this method never actually returns Err, but keeps a Result return type for parity with the rest of this module’s fallible methods.

Errors

Never returns an error; the signature is Result for parity with the rest of this module.

Panics

Panics if deployer_config.helm is None.

pub fn undeploy( &self, deployer_config: &DeployerConfig, caproni_config: &CaproniConfig, ) -> Result<(), HelmError>

Ported from Undeploy. Uninstalls the release if it’s deployed, and does nothing if it isn’t, so removing twice is safe.

Errors

Returns HelmError::NotHelmDeployer if deployer_config is not a helm deployer or has no helm block, and a HelmError::Backend if helm uninstall fails.

pub fn prepare_chart_source( &self, deployer_config: &DeployerConfig, caproni_config: &CaproniConfig, ) -> Result<(String, Box<dyn FnOnce()>), HelmError>

Ported from prepareChartSource. Determines the chart reference to pass to helm install/helm upgrade.

Four chart source modes:

1. Edit mode with repository — uses the local cloned directory path.
2. Repository-based chart — runs helm repo add/update, returns a repo/chart reference.
3. Direct chart reference (OCI, local path, etc.) — returns the chart string as-is.
4. Absolute http(s) URL — fetches the chart and returns a local packaged copy.

Every mode that ends at a chart directory has its dependencies resolved first, since a chart source tree vendors only its in-tree subcharts. Modes ending at a repository, a registry, or an archive are left alone.

Errors

Returns an error if deployer_config has no helm block, the repository named by edit mode is not found, helm.release is missing when required, adding/updating the configured helm repository fails, fetching a URL chart fails, or resolving a chart’s dependencies fails.

pub fn validate( &self, deployer_config: &DeployerConfig, caproni_config: &CaproniConfig, ) -> Result<(), HelmError>

Ported from Validate. Validates the helm deployer configuration and referenced files.

Errors

Returns an error if deployer_config is not a helm deployer, helm.release is missing when required, release.version is set without helm.repository, a dynamic override is invalid, or a referenced file doesn’t exist.

Panics

Never panics: the deployer_config.helm.is_none() case is checked and returned as an error before the .expect() below runs.

Trait Implementations

impl<B: HelmBackend> Manager for Manager<B>

Lets the orchestrator drive a helm Manager through the registry.

fn deployer_type(&self) -> String

The deployer type that this manager handles (e.g. "helm").

fn deploy( &self, deployer_config: &DeployerConfig, cfg: Option<&Container>, ) -> Result<(), Box<dyn Error + Send + Sync>>

Deploys the application to the cluster. If the application is already deployed, this updates it to match the current configuration.

fn undeploy( &self, deployer_config: &DeployerConfig, caproni_config: &CaproniConfig, ) -> Result<(), Box<dyn Error + Send + Sync>>

Removes this deployment from the cluster.

fn status( &self, deployer_config: &DeployerConfig, caproni_config: &CaproniConfig, ) -> Result<Status, Box<dyn Error + Send + Sync>>

Returns the current status of the deployment. Returns an error if unable to determine deployment state.

fn validate( &self, deployer_config: &DeployerConfig, caproni_config: &CaproniConfig, ) -> Result<(), Box<dyn Error + Send + Sync>>

Validates the deployer configuration and referenced files. Returns Ok(()) if valid, or an error describing validation failures. Files in uncloned repository directories should not cause validation to fail.
