Struct ListIndex 

pub struct ListIndex { /* private fields */ }

Ranks the rows of a list against a query, for surfaces that rebuild their rows on every query or change (commands, windows, actions).

The rows’ text is indexed once and kept until it changes, so asking again with the same rows only searches. Rows are identified by position.

Implementations

impl ListIndex

pub const fn new(matching: Matching) -> ListIndex

pub fn ranks<'a, R>( &self, query: &str, rows: impl IntoIterator<Item = R>, ) -> Vec<Option<i32>>

where R: IntoIterator<Item = (&'a str, FieldWeight)>,

Each row’s rank for query, or None where it does not match. An empty query matches every row at rank 0.

Trait Implementations

impl Debug for ListIndex

fn fmt(&self, formatter: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for ListIndex

Names in a short list are what a person half remembers, so the default also matches words spread over fields and typos.

fn default() -> ListIndex

Returns the “default value” for a type.
