WriteOp

Struct WriteOp 

Source
pub struct WriteOp<'a, H>(/* private fields */);
Expand description

A positional write borrowing its handle and payload without copying either. Construction performs no I/O or allocation. Does not change the file cursor. Uses the same storage definition as the native crate::WriteOp.
