CompressContext

Struct CompressContext 

Source
pub struct CompressContext { /* private fields */ }
Expand description

Reusable compression context that amortizes hash table and buffer allocations.

Holds internal state (hash tables, output buffer, block encoder workspace) across calls. Useful when compressing many small inputs in a loop.

let mut ctx = zrip::CompressContext::new(1).unwrap();
for i in 0..10 {
    let data = format!("message {i}").repeat(100);
    let compressed = ctx.compress(data.as_bytes()).unwrap();
    assert!(compressed.len() < data.len());
}

Implementations§

Source§

impl CompressContext

Source

pub fn new(level: i32) -> Result<Self, CompressError>

Creates a new context for the given compression level (-7..=4).

Source

pub fn with_dict(level: i32, dict: Dictionary) -> Result<Self, CompressError>

Creates a new context with a pre-loaded dictionary.

Source

pub fn compress(&mut self, input: &[u8]) -> Result<Cow<'_, [u8]>, CompressError>

Compresses input using the context’s level and optional dictionary.

Source

pub fn compress_with_dict( &mut self, input: &[u8], dict: &Dictionary, ) -> Result<Cow<'_, [u8]>, CompressError>

Compresses input using an ad-hoc dictionary (overrides the stored one).
