[−][src]Enum cdrs_temp::compression::Compression
Enum which represents a type of compression. Only non-startup frame's body can be compressen.
Variants
lz4 compression
snappy compression
Non compression
Implementations
impl Compression
[src]
pub fn encode(&self, bytes: Vec<u8>) -> Result<Vec<u8>, CompressionError>
[src]
It encodes bytes
basing on type of Compression
..
Examples
use cdrs::compression::Compression; let snappy_compression = Compression::Snappy; let bytes = String::from("Hello World").into_bytes().to_vec(); let encoded = snappy_compression.encode(bytes.clone()).unwrap(); assert_eq!(snappy_compression.decode(encoded).unwrap(), bytes);
pub fn decode(&self, bytes: Vec<u8>) -> Result<Vec<u8>, CompressionError>
[src]
It decodes bytes
basing on type of compression.
Examples
use cdrs::compression::Compression; let lz4_compression = Compression::Lz4; let bytes = String::from("Hello World").into_bytes().to_vec(); let encoded = lz4_compression.encode(bytes.clone()).unwrap(); let len = encoded.len() as u8; let mut input = vec![0, 0, 0, len]; input.extend_from_slice(encoded.as_slice()); assert_eq!(lz4_compression.decode(input).unwrap(), bytes);
pub fn as_str(&self) -> Option<&'static str>
[src]
It transforms compression method into a &str
.

impl<'a> From<&'a str> for Compression
[src]
