Struct pest::pratt_parser::PrattParserMap

pub struct PrattParserMap<'pratt, 'i, R, F, T>where
    R: RuleType,
    F: FnMut(Pair<'i, R>) -> T,{ /* private fields */ }

Product of calling map_primary on PrattParser, defines how expressions should be mapped.

Implementations

impl<'pratt, 'i, R, F, T> PrattParserMap<'pratt, 'i, R, F, T>where
    R: RuleType + 'pratt,
    F: FnMut(Pair<'i, R>) -> T,

pub fn map_prefix<X>(self, prefix: X) -> Selfwhere
    X: FnMut(Pair<'i, R>, T) -> T + 'i,

Maps prefix operators with closure prefix.

pub fn map_postfix<X>(self, postfix: X) -> Selfwhere
    X: FnMut(T, Pair<'i, R>) -> T + 'i,

Maps postfix operators with closure postfix.

pub fn map_infix<X>(self, infix: X) -> Selfwhere
    X: FnMut(T, Pair<'i, R>, T) -> T + 'i,

Maps infix operators with a closure infix.

pub fn parse<P: Iterator<Item = Pair<'i, R>>>(&mut self, pairs: P) -> T

The last method to call on the provided pairs to execute the Pratt parser (previously defined using map_primary, map_prefix, map_postfix, and map_infix methods).
