Struct piston_meta::meta_rules::FastSelect

pub struct FastSelect {
    pub table: [u8; 256],
    pub args: Vec<Rule>,
    pub tail: bool,
    pub debug_id: DebugId,
}

Stores information about select.

Fields

table: [u8; 256]

The table used to look up sub-rule from next byte.

args: Vec<Rule>

The rules to select from using the table. If tail is true, the last rule is used in table lookup fails.

tail: bool

Whether the last rule is used when table lookup fails.

debug_id: DebugId

A debug id to track down the rule generating an error.

Methods

impl FastSelect

pub fn parse(
    &self,
    tokens: &mut Vec<Range<MetaData>>,
    state: &TokenizerState,
    read_token: &ReadToken,
    refs: &[Rule]
) -> ParseResult<TokenizerState>

Parses select with lookup table.
