Struct BeamSearchConfig 

pub struct BeamSearchConfig {
    pub max_blocks: usize,
    pub max_explorations: Option<usize>,
}

Beam search configuration controlling how the fusion optimizer explores independent blocks of operations.

Fields

max_blocks: usize

Maximum number of independent blocks explored during the fusion search.

Higher values can find better fusion opportunities at the cost of more cache misses in the fusion cache.

max_explorations: Option<usize>

Stop exploring new optimizations after this many explorations (per stream).

Each cache miss runs the (relatively expensive) optimizer to build a new optimization. A graph whose relative form changes every step never caches, so it re-explores forever. Once this cap is reached, cache-missing segments execute unfused (no optimizer work, nothing added to the cache) instead. Cache hits are unaffected, so already-cached stable graphs keep replaying. None (the default) never disables exploration.
