Struct ValueMatcher 

pub struct ValueMatcher { /* private fields */ }

A search text prepared for matching many values.

Implementations

impl ValueMatcher

pub const DEFAULT_MIN_SIMILARITY: f64 = 0.6

The least similarity a similar match needs when none is given.

pub fn new( text: &str, matching: TextMatch, case_sensitive: bool, min_similarity: Option<f64>, ) -> Self

Prepares text for matching (case-insensitive unless case_sensitive); min_similarity applies to similar only.

pub fn matching(&self) -> TextMatch

How the text must match.

pub fn matches(&self, value: &Json) -> bool

Whether value matches.

pub fn matches_text(&self, text: &str) -> bool

Whether a text value matches, as Self::matches does for the string text, without building the JSON value.

pub fn may_match(&self, ty: LogicalType) -> bool

Whether a value of ty can match: false only when no rendering of that type can contain the text, so a caller may skip the type’s values without changing the result. Numbers render with digits, ., -, + and e; booleans as true/false; datetimes as a year-first date with an optional T…Z time. similar and a text that reads as a date can match any type.

pub fn similarity(&self, value: &Json) -> f64

How close value is to the text, from 0 to 1 (see similarity); arrays score their closest element.
