Struct ChunkIteratorMut 

pub struct ChunkIteratorMut<'a> { /* private fields */ }

Mutable iterator over fixed-size chunks of a memory-mapped file.

This iterator provides mutable access to chunks, but due to Rust’s borrowing rules, it cannot yield multiple mutable references simultaneously. Instead, it provides a callback-based interface.

Implementations

impl<'a> ChunkIteratorMut<'a>

pub fn for_each_mut<F, E>(self, f: F) -> Result<Result<(), E>>

where F: FnMut(u64, &mut [u8]) -> Result<(), E>,

Process each chunk with a callback function.

The callback receives the offset and a mutable slice for each chunk.
