Struct TriggerPattern 

pub struct TriggerPattern { /* private fields */ }

A regular expression that switches a lazy grammar on.

llama_grammar_trigger_pattern. Holds two compiled forms because upstream’s find uses two: std::regex_match (the whole buffer must match) is tried first for a pattern written ^...$, and std::regex_search (match anywhere) is the fallback for every pattern. The two can disagree about which alternative matches, and therefore about where the first capture group starts.

Implementations

impl TriggerPattern

pub fn new(pattern: &str) -> Result<Self, GrammarError>

Compile pattern.

pub fn pattern(&self) -> &str

The pattern as written.

pub fn find(&self, input: &str) -> Result<Option<usize>, GrammarError>

Where the grammar should start reading input, or None if this pattern does not match it yet.

llama_grammar_trigger_pattern::find, whose npos is this None.

Trait Implementations

impl Clone for TriggerPattern

fn clone(&self) -> TriggerPattern

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TriggerPattern

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

Formats the value using the given formatter.

impl Eq for TriggerPattern

impl PartialEq for TriggerPattern

Two patterns are the same trigger when they are the same source. The compiled forms are a function of it.

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

Equality operator ==.

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

Inequality operator !=.
