    ) -> Result<(), Error<Self::FsError>>;
}

A file that contains directory entries. No two directory entries in the same directory have the same name.

Defined in this POSIX definition.

Required Methods

fn add_entry( &mut self, name: UnixStr<'_>, file_type: Type, permissions: Permissions, user_id: Uid, group_id: Gid, ) -> Result<TypeWithFile<Self>, Error<Self::FsError>>

Adds a new empty entry to the directory, meaning that a new file will be created.

Errors

Returns an EntryAlreadyExist error if the entry already exist.

Returns an Error::IO if the device on which the directory is located could not be written.

fn remove_entry( &mut self, name: UnixStr<'_>, ) -> Result<(), Error<Self::FsError>>

Removes an entry from the directory.

Errors

Returns an NotFound error if there is no entry with the given name in this directory.

Returns an Error::IO if the device on which the directory is located could not be written.

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.
