Struct Query 

pub struct Query {
    pub all: Vec<String>,
    pub any: Vec<Vec<String>>,
    pub none: Vec<String>,
    pub raw: String,
}

A parsed search-box query.

Eagle flattens the expression tree into three lists: every AND term must match, every OR group must have one member match, and no NOT term may match. Nested groups are flattened the same lossy way, so dog || (cat black) is the OR of dog and the literal cat black.

Fields

all: Vec<String>

any: Vec<Vec<String>>

none: Vec<String>

raw: String

The whole query, lower-cased; matched as one substring if the terms fail.

Implementations

impl Query

pub fn parse(q: &str) -> Query

pub fn is_empty(&self) -> bool

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

Whether text (already lower-cased) satisfies the query.

pub fn fuzzy_score(&self, text: &str) -> Option<usize>

Typo-tolerant match (falcon’s own, not Eagle’s). Some(0) when Query::matches passes; otherwise Some(cost), the total number of edits needed for every AND term and one member of every OR group to match the start of some word in text, or None if that’s too many. NOT terms stay exact. See the Search chapter for the rules.

Trait Implementations

impl Clone for Query

fn clone(&self) -> Query

impl Debug for Query

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

impl Default for Query

fn default() -> Query

Returns the “default value” for a type.

impl PartialEq for Query

fn eq(&self, other: &Query) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
