Enum PairTruncationPolicy 

#[non_exhaustive]
pub enum PairTruncationPolicy {
    LongestFirst,
    PreserveQueryToThreeQuarters,
}

How a pair longer than max_length is cut to fit; each rerank entry names its own.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

LongestFirst

The tokenizer’s default: remove one token at a time from whichever side is longer until the pair fits.

PreserveQueryToThreeQuarters

FlagEmbedding’s policy: the query alone is cut to three quarters of max_length, then only the document, to zero tokens if need be; at a max_length of 12 or less the pair can still exceed it, as in the reference.
