Struct rscache::codec::DecodedBuffer

pub struct DecodedBuffer {
    pub compression: Compression,
    pub len: usize,
    pub version: Option<i16>,
    // some fields omitted
}

Decodes a cache buffer with some additional data.

This struct can be useful if you need more details then just the decoded data.

Examples

TryFrom<&[u8]> -> DecodedBuffer:

use rscache::codec::DecodedBuffer;
use std::convert::TryFrom;

let buffer = cache.read(2, 10)?;
let decoded = DecodedBuffer::try_from(buffer.as_slice())?;

assert_eq!(decoded.compression, Compression::Bzip2);
assert_eq!(decoded.len, 886570);
assert_eq!(decoded.version, Some(12609));

Getting the inner buffer: This conversion is free.

let buffer = cache.read(2, 10)?;
let decoded = DecodedBuffer::try_from(buffer.as_slice())?;

let inner_buffer: Vec<u8> = decoded.into_vec();

Fields

compression: Compression

len: usize

version: Option<i16>

Implementations
