Struct TournamentConfig 

pub struct TournamentConfig {
    pub codecs: Vec<String>,
    pub min_size_threshold: u32,
    pub skip_for_binary: bool,
    pub short_circuit_threshold: u32,
}

Compression tournament settings.

Fields

codecs: Vec<String>

Codecs to try in the tournament (ordered fast → slow). The writer iterates these in order and stops early when short_circuit_threshold is met.

min_size_threshold: u32

Minimum chunk size for the tournament to try a codec.

skip_for_binary: bool

Skip tournament for binary class (use binary_codec directly).

short_circuit_threshold: u32

Short-circuit the tournament once a codec achieves this ratio or better. Stored as per-mille (parts per 1000) so it serialises as an integer — 250 means “accept the moment a codec reaches 25% of original size”. 0 disables short-circuit (try every codec).

For example, on a highly-compressible CSV chunk, LZ4 typically reaches ~10% ratio in microseconds; the short-circuit lets us accept that and skip the much-slower Brotli pass we would otherwise run for ratio parity. On hard-to-compress text where LZ4 only reaches ~40%, the tournament continues to Brotli to preserve ratio.
