Struct Pattern 

pub struct Pattern {
    pub properties: Vec<Property>,
    pub predicates: Vec<Predicate>,
    pub local: Option<bool>,
    pub priority: i32,
    /* private fields */
}

Properties and custom predicates for one query pattern.

Fields

properties: Vec<Property>

Property settings in runtime order.

predicates: Vec<Predicate>

Custom predicates applied after runtime matching.

local: Option<bool>

Required local-binding state, or None for either state.

priority: i32

Compiled highlight priority, defaulting to 100.

Implementations

impl Pattern

pub fn new( properties: Vec<Property>, predicates: Vec<(String, Vec<Argument>)>, local: Option<bool>, ) -> Result<Self, Error>

Compile custom predicates and retain normalized pattern metadata.

Errors

Returns Error::Query for unsupported or malformed custom predicates.

pub fn property(&self, key: &str) -> Option<&Property>

Return the first property matching the key.

pub fn value(&self, key: &str) -> Option<&str>

Return the first matching property’s value, if present.
