Required Methods

fn read(self: Vc<Self>, fs_path: FileSystemPath) -> Vc<FileContent>

where Self: Sized,

fn read_link(self: Vc<Self>, fs_path: FileSystemPath) -> Vc<LinkContent>

where Self: Sized,

Reads the target of a symbolic link (or of a junction point on Windows).

The base of the returned LinkContent::Link target depends on the link’s LinkType: root-relative and normalized for LinkType::ABSOLUTE links, or the raw link-relative on-disk value otherwise.

Returns LinkContent::Invalid if the target points outside of the filesystem root, and LinkContent::NotFound if fs_path doesn’t exist or isn’t a link.

fn raw_read_dir( self: Vc<Self>, fs_path: FileSystemPath, ) -> Vc<RawDirectoryContent>

where Self: Sized,

fn write( self: Vc<Self>, fs_path: FileSystemPath, content: Vc<FileContent>, ) -> Vc<()>

where Self: Sized,

fn write_link( self: Vc<Self>, fs_path: FileSystemPath, target: Vc<LinkContent>, ) -> Vc<()>

where Self: Sized,

See FileSystemPath::write_symbolic_link_dir.

fn metadata(self: Vc<Self>, fs_path: FileSystemPath) -> Vc<FileMeta>

where Self: Sized,

Provided Methods

fn root(self: Vc<Self>) -> Vc<FileSystemPath>

where Self: Sized,

Returns the path to the root of the file system.

Dyn Compatibility

This trait is dyn compatible.

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