Trait SnapshotSink 

pub trait SnapshotSink {
    // Required methods
    fn write(&mut self, bytes: &[u8]) -> Result<(), Error>;
    fn patch(&mut self, at: u64, bytes: &[u8]) -> Result<(), Error>;
}

A byte sink for streaming a snapshot without materializing the whole image: write appends in file order, patch overwrites a short run at an absolute offset — used once for the header file-hash field, the only non-sequential write, done after the body has streamed.

Required Methods

fn write(&mut self, bytes: &[u8]) -> Result<(), Error>

Appends bytes at the current position.

Errors

Whatever the underlying sink reports (e.g. an I/O error).

fn patch(&mut self, at: u64, bytes: &[u8]) -> Result<(), Error>

Overwrites bytes at absolute offset at (already-written region).

Errors

Whatever the underlying sink reports.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
