Struct PackagedDataBackend 

pub struct PackagedDataBackend { /* private fields */ }

A packaged compressed-data backend.

Implementations

impl PackagedDataBackend

pub fn new() -> Self

Creates a new packaged-data backend backed by the checked-in fixture.

pub fn from_artifact(artifact: CompressedArtifact) -> Self

Creates a packaged-data backend from an explicit artifact.

pub fn from_bytes(bytes: &[u8]) -> Result<Self, PackagedArtifactLoadError>

Creates a packaged-data backend from decoded artifact bytes.

See crate::packaged_backend_from_bytes for an end-to-end example that encodes the checked-in artifact and reloads it through this constructor.

pub fn from_path( path: impl AsRef<Path>, ) -> Result<Self, PackagedArtifactLoadError>

Creates a packaged-data backend from an artifact file.

See crate::packaged_backend_from_path for an end-to-end example that writes the checked-in artifact to a temporary file and reloads it through this constructor.
