Struct TypePermissions 

pub struct TypePermissions(/* private fields */);

Available on crate feature ext2 only.

The bitwise negation (!) of the bits in a flags value, truncating the result.

impl TypePermissions

Each yielded flags value will correspond to a defined named flag. Any unknown bits will be yielded together as a final flags value.

This method is like iter, except only yields bits in contained named flags. Any unknown bits, or bits not corresponding to a contained flag will not be yielded.

impl TypePermissions

pub const fn file_type(self) -> Self

Returns the type component of the TypePermissions.
