Struct CodecOptions 

pub struct CodecOptions {
    pub level: i32,
    pub long_window_log: u32,
    pub dict: Option<Vec<u8>>,
    pub choice: CodecChoice,
    pub effort: u8,
}

Fields

level: i32

long_window_log: u32

Upper bound for the zstd window log; the window is otherwise sized to the block.

dict: Option<Vec<u8>>

choice: CodecChoice

effort: u8

Codec-choice effort for CodecChoice::Best, 1..=5 (values outside are clamped): 1 = zstd only (identical to CodecChoice::Zstd), 2 = zstd or xz decided on a sample of the block, 3 = zstd, xz or PPMd (text) decided on a sample, 4 = 3 plus xz on the whole block when PPMd won the sample, 5 = every codec on every block (the default; today’s full trial, the same code path byte for byte). Blocks of at most sample_full_trial_max bytes always run the full trial. Other choices ignore it. See sample for the sampling rule.
