Struct PyRuntimeConfig 

pub struct PyRuntimeConfig {
    pub pyodide_version: String,
    pub pyodide_package_dir: Option<PathBuf>,
    pub default_language: RuntimeLanguage,
    pub snapshot: SnapshotConfig,
    pub hooks: HostHooks,
    pub budget_override: Option<InvocationLimits>,
    pub reset_policy: ResetPolicy,
    pub host_capabilities: Vec<String>,
    pub warm_state: Option<WarmState>,
}

Configuration applied when constructing PyRuntime or pool members.

Fields

pyodide_version: String

Bundled Pyodide version string (usually derived from build-time assets).

pyodide_package_dir: Option<PathBuf>

Filesystem directory used to resolve Pyodide wheel and metadata requests.

When the crate is compiled with the full-pyodide-packages feature this defaults to the build-script managed cache extracted into OUT_DIR. Hosts can override it programmatically to avoid relying on process-wide environment variables.

default_language: RuntimeLanguage

Default guest language selected when manifests/descriptors omit one.

snapshot: SnapshotConfig

Snapshot-related configuration.

hooks: HostHooks

Host lifecycle hooks executed around warm snapshot capture/restore.

budget_override: Option<InvocationLimits>

Optional global budget override applied to every session.

reset_policy: ResetPolicy

Runtime reset behaviour after each invocation.

host_capabilities: Vec<String>

Host capabilities enabled for exposed native APIs.

warm_state: Option<WarmState>

Optional prebuilt warm state (snapshot + overlay).

Implementations

impl PyRuntimeConfig

pub fn pyodide_package_dir(&self) -> Option<&PathBuf>

pub fn clear_pyodide_package_dir(&mut self)

Clears any explicit Pyodide package directory override.

pub fn with_pyodide_package_dir<P: Into<PathBuf>>(self, path: P) -> Self

Returns a new configuration with the provided Pyodide package directory.

pub fn without_pyodide_package_dir(self) -> Self

Returns a new configuration without an explicit Pyodide package directory override.
