Struct RationerBuilder

Source

pub struct RationerBuilder { /* private fields */ }

Expand description

Builder for Rationer. Configure once, then .build().

Implementations§

Source §

impl RationerBuilder

Source

pub fn concurrency(self, c: Concurrency) -> Self

Pick a backend. See Concurrency.

Source

pub fn threads(self, n: usize) -> Self

Set the rayon worker count for CPU-side work (filtering, per-pair recursion, assemble). None (default) uses the global rayon pool. Some(1) forces single-threaded execution.

Source

pub fn delta(self, d: f64) -> Self

Approximate-RO knob (Phase 3). delta = 0.0 (default) means exact Ratcliff-Obershelp — bit-identical to Python difflib. delta ∈ (0, 1] trades a bounded amount of accuracy for fewer chain walks inside longest_in: the suffix-link chain is capped at roughly 1/√delta ascensions, which empirically only fires on the long-tail (p99+) cases. Property-tested in tests/approx_ro.rs: actual worst-case absolute RO deviation stays below delta on canonical-Python corpora (typically several times tighter).

Source

pub fn build(self) -> Rationer

Materialize the handle. Acquires Metal device + IOPM boost assertion (when GPU is in the requested concurrency mode); allocates a dedicated rayon pool if threads is set.
