Struct ArtifactStore 

pub struct ArtifactStore { /* private fields */ }

In-memory artifact store.

Implementations

impl ArtifactStore

pub fn new() -> Self

Construct an empty store with a 1-hour default retention.

pub const fn with_default_retention(self, duration: Duration) -> Self

Override the default retention duration.

pub fn put( &self, media_type: impl Into<String>, data: &str, retain_seconds: Option<u64>, sha256: Option<String>, ) -> Result<ArtifactRef, ARCPError>

Store a base64-encoded body. Returns the new ArtifactRef.

Errors

Returns ARCPError::InvalidArgument if data is not valid base64 or exceeds the inline size cap (4 MiB after base64 decode, per PLAN.md §A4.11).

pub fn fetch(&self, id: &ArtifactId) -> Result<(String, String), ARCPError>

Fetch an artifact by id. Returns base64-encoded body alongside its media_type.

Errors

Returns ARCPError::NotFound if the artifact is unknown or has expired (the store sweeps lazily on read).

pub fn release(&self, id: &ArtifactId)

Drop an artifact from the store (regardless of expiry).

pub fn len(&self) -> usize

Number of stored artifacts (does not sweep).

pub fn is_empty(&self) -> bool

True if the store is empty.

pub fn sweep_expired(&self) -> usize

Sweep expired artifacts. Returns the number removed.
