Struct hime_redist::parsers::LRProduction

pub struct LRProduction {
    pub head: usize,
    pub head_action: TreeAction,
    pub reduction_length: usize,
    pub bytecode: Vec<LROpCode>,
}

Represents a rule’s production in a LR parser The binary representation of a LR Production is as follow: — header u16: head’s index u8: 1=replace, 0=nothing u8: reduction length u8: bytecode length in number of op-code — production’s bytecode array of LROpCode

Fields

head: usize

Index of the rule’s head in the parser’s array of variables

head_action: TreeAction

Action of the rule’s head (replace or not)

reduction_length: usize

Size of the rule’s body by only counting terminals and variables

bytecode: Vec<LROpCode>

Bytecode for the rule’s production
