Struct PreparedRationer 

pub struct PreparedRationer<'r> { /* private fields */ }

Reusable corpus + SAMs built by Rationer::prepare. Hold this across many ratio_many_idx calls to amortize SAM building and the GPU upload over the lifetime of the string set. Borrowing the Rationer keeps the Metal device and thread pool wiring alive.

Implementations

impl PreparedRationer<'_>

pub fn len(&self) -> usize

Number of strings in the prepared corpus.

pub fn is_empty(&self) -> bool

True iff len() == 0.

pub fn ratio_many_idx(&self, pairs: &[(u32, u32)]) -> Vec<f64>

Batched Ratcliff-Obershelp ratio over a pair list referencing the prepared strings by index ((i, j) ⇒ ratio(strings[i], strings[j])). All SAM / GPU-corpus state is reused from prepare(), so a long-lived PreparedRationer paying its build cost once can serve many queries at the kernel-pure GPU throughput.

Panics

Panics if any pair index is out of bounds.
