Struct ChainState 

pub struct ChainState {
    pub in_chain: bool,
    pub chain_matched: bool,
    pub captures: Vec<String>,
    pub chain_start: Option<usize>,
}

Track chain state during rule execution.

Fields

in_chain: bool

Whether we’re currently in a chain.

chain_matched: bool

Whether the current chain has matched so far.

captures: Vec<String>

Accumulated captures from chain.

chain_start: Option<usize>

Starting rule index of current chain.

Implementations

impl ChainState

pub fn new() -> Self

Create a new chain state.

pub fn start_chain(&mut self, rule_idx: usize)

Start a new chain.

pub fn continue_chain(&mut self, matched: bool, captures: &[String])

Continue chain with match result.

pub fn end_chain(&mut self) -> bool

End the current chain.

pub fn reset(&mut self)

Reset chain state (on match failure).
