Trait FileExt

pub trait FileExt: AsRawFd {
    // Provided methods
    fn get_xattr<N>(&self, name: N) -> Result<Option<Vec<u8>>>
       where N: AsRef<OsStr> { ... }
    fn set_xattr<N>(&self, name: N, value: &[u8]) -> Result<()>
       where N: AsRef<OsStr> { ... }

       where N: AsRef<OsStr> { ... }
    fn list_xattr(&self) -> Result<XAttrs> { ... }
}

Extension trait to manipulate extended attributes on File-like objects.

Provided Methods

fn get_xattr<N>(&self, name: N) -> Result<Option<Vec<u8>>>

where N: AsRef<OsStr>,

Get an extended attribute for the specified file.

fn set_xattr<N>(&self, name: N, value: &[u8]) -> Result<()>

where N: AsRef<OsStr>,

Set an extended attribute on the specified file.

fn remove_xattr<N>(&self, name: N) -> Result<()>

where N: AsRef<OsStr>,

Remove an extended attribute from the specified file.

fn list_xattr(&self) -> Result<XAttrs>

List extended attributes attached to the specified file.

Note: this may not list all attributes. Speficially, it definitely won’t list any trusted attributes unless you are root and it may not list system attributes.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
