Types

structIoSlice

struct IoSlice

A borrowed (pointer, length) buffer slice for vectored I/O.

Fields

base: *const u8

Pointer to the first byte of the slice.

len: i64

Number of bytes in the slice.

Functions

fnio_slice

fn io_slice(ptr: *const u8, len: i64) -> IoSlice

Builds an IoSlice from a raw pointer and length.

fnwrite_all

fn write_all(w: &mut W, buf: *const u8, len: i64) -> i64

Writes all len bytes from buf, looping over partial writes. Returns 0 on success, or the negative errno from the first failing write.
