MetadataFileSystem

Trait MetadataFileSystem 

Source
pub trait MetadataFileSystem:
    Debug

    fn persist_atomic(&self, target: &Path, bytes: &[u8]) -> RuntimeResult<()>;
}
Expand description

Filesystem abstraction used by the metadata actor.

Implementations must not publish partial target files. Production callers should use LocalMetadataFileSystem; the abstraction also permits deterministic fault injection without relying on a particular host filesystem.

Required Methods§

Source

fn persist_atomic(&self, target: &Path, bytes: &[u8]) -> RuntimeResult<()>

Atomically persists one immutable snapshot.

§Errors

Returns a typed error that identifies the failed durability step and retains the original I/O source.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
