Implementations

impl TsConfig

pub const fn stems(self) -> bool

v7.38.18 — does this configuration stem at all?

The four places that decide stopwords and stemming used to ask config.stems(), a two-valued question. Adding a language to an enum those read as a boolean would have made it tokenise without dropping a stopword and without stemming — silently, since every token still comes out.

pub fn stopwords(self) -> Option<&'static [&'static str]>

This configuration’s stopword list, or None when it has none.

pub fn is_stopword(self, w: &str) -> bool

Is w a stopword under this configuration?

pub fn stem(self, w: &str) -> String

The stem w reduces to under this configuration.

pub fn from_name(name: &str) -> Option<Self>

Resolve a PG text-search config name. The PG-qualified form pg_catalog.<name> is accepted too. Returns None for any other name so the caller can produce a clear “config not implemented” error listing what is supported.
