Struct IoWriter 

pub struct IoWriter<W> { /* private fields */ }

Wraps a type that implements io::Write and equips it with Writer.

Examples

use rkyv::rancor::{Error, Strategy};
let mut io_writer = IoWriter::new(Vec::new());
// In most cases, calling a method like `serialize` will wrap the writer in
// a Strategy for us.
let mut writer = Strategy::<_, Error>::wrap(&mut io_writer);
assert_eq!(writer.pos(), 0);
writer.write(&[0u8, 1u8, 2u8, 3u8]);
assert_eq!(writer.pos(), 4);
let buf = io_writer.into_inner();
assert_eq!(buf.len(), 4);
assert_eq!(buf, vec![0u8, 1u8, 2u8, 3u8]);

Implementations

impl<W> IoWriter<W>

pub fn new(inner: W) -> Self

Creates a new serializer from a writer.

pub fn with_pos(inner: W, pos: usize) -> Self

Creates a new serializer from a writer, and assumes that the underlying writer is currently at the given position.

pub fn into_inner(self) -> W

Consumes the serializer and returns the internal writer used to create it.

Trait Implementations

impl<W> Positional for IoWriter<W>

fn pos(&self) -> usize

Returns the current position of the writer.

impl<W: Write, E: Source> Writer<E> for IoWriter<W>

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

Attempts to write the given bytes to the serializer.
