Trait fastobo::parser::FromPair

pub trait FromPair<'i>: Sized {
    const RULE: Rule;

    unsafe fn from_pair_unchecked(
        pair: Pair<'i, Rule>,
        cache: &Cache
    ) -> Result<Self, SyntaxError>;

    fn from_pair(
        pair: Pair<'i, Rule>,
        cache: &Cache
    ) -> Result<Self, SyntaxError> { ... }
}

A trait for structures that can be parsed from a pest::Pair.

Required Associated Constants

const RULE: Rule

The production rule the pair is expected to be obtained from.

Required Methods

unsafe fn from_pair_unchecked(
    pair: Pair<'i, Rule>,
    cache: &Cache
) -> Result<Self, SyntaxError>

Create a new instance from a Pair without checking the rule.

Safety

May panic if the pair was not produced by the right rule, i.e. pair.as_rule() != <Self as FromPair>::RULE.

Provided Methods

fn from_pair(pair: Pair<'i, Rule>, cache: &Cache) -> Result<Self, SyntaxError>

Create a new instance from a Pair.
