Asynchronous filesystem boundary used by harness tools.

The harness uses this boundary for diagnostic path resolution and descriptor-relative opening, keeping repository containment inside the filesystem operation.

Required Methods

fn canonicalize<'life0, 'life1, 'async_trait>( &'life0 self, path: &'life1 Path, ) -> Pin<Box<dyn Future<Output = Result<PathBuf>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Resolves a path to its canonical absolute representation.

Errors

Returns an I/O error when the path cannot be resolved.

fn open_beneath<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, root: &'life1 Path, path: &'life2 Path, ) -> Pin<Box<dyn Future<Output = Result<Box<dyn AsyncRead + Send + Unpin>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Opens a repository-relative file without following symlinks beneath root.

Errors

Returns an I/O error when path is invalid, traverses a symlink, does not name a regular file, or cannot be opened for reading.

Dyn Compatibility

This trait is dyn compatible.

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