Struct rkyv::ArchiveWriter

pub struct ArchiveWriter<W: Write> { /* fields omitted */ }

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

Examples

use rkyv::{ArchiveWriter, Write};

let mut writer = ArchiveWriter::new(Vec::new());
assert_eq!(writer.pos(), 0);
writer.write(&[0u8, 1u8, 2u8, 3u8]);
assert_eq!(writer.pos(), 4);
let buf = writer.into_inner();
assert_eq!(buf.len(), 4);
assert_eq!(buf, vec![0u8, 1u8, 2u8, 3u8]);

Implementations

impl<W: Write> ArchiveWriter<W>

pub fn new(inner: W) -> Self

Creates a new archive writer from a writer.

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

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

pub fn into_inner(self) -> W

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

Trait Implementations

impl<W: Write> Write for ArchiveWriter<W>

type Error = Error

The errors that may occur while writing.

pub fn pos(&self) -> usize

Returns the current position of the writer.

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

Attempts to write the given bytes to the writer.
