Helpers for writing a reply for read_dir or read_dir_plus.

This trait is implemented on Cursor<&mut Vec<u8>>. To write directory entries, create an appropriately-sized vector with Vec::with_capacity, wrap it in a Cursor, and write entries using the methods of this trait.

The methods of this trait ensure that the entries are correctly aligned in the buffer.

Required Methods

fn dir_entry( &mut self, name: impl AsRef<LxStr>, inode_nr: u64, offset: u64, file_type: u32, ) -> bool

Write a directory entry to the buffer.

Returns true if the entry fit in the buffer; otherwise, false.

fn dir_entry_plus( &mut self, name: impl AsRef<LxStr>, offset: u64, entry: fuse_entry_out, ) -> bool

Write a directory entry for read_dir_plus to the buffer.

Returns true if the entry fit in the buffer; otherwise, false.

fn check_dir_entry_plus(&self, name: impl AsRef<LxStr>) -> bool

Checks whether an entry for read_dir_plus will fit in the buffer without writing it.

Returns true if the entry fit in the buffer; otherwise, false.

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.
