Trait Implementations§

impl Clone for VfsError

fn clone(&self) -> VfsError

Returns a duplicate of the value. Read more

1.0.0 · Source§

impl From<DeviceError> for VfsError

fn from(e: DeviceError) -> Self

Converts to this type from the input type.

impl PartialEq for VfsError

fn eq(&self, other: &VfsError) -> bool

Tests for self and other values to be equal, and is used by ==.

1.0.0 · Source§

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
