Extension methods for syn::parse::ParseBuffer.

Required Methods

fn look_and_eat<T: Eat>(&self, token: T, lookahead: &Lookahead1<'a>) -> bool

fn eat<T: Eat>(&self, t: T) -> bool

Consumes a token T if present.

fn eat2<T1: Eat, T2: Eat>(&self, t1: T1, t2: T2) -> bool

Consumes two tokens T1 T2 if present in that order.

fn eat3<T1: Eat, T2: Eat, T3: Eat>(&self, t1: T1, t2: T2, t3: T3) -> bool

Consumes three tokens T1 T2 T3 if present in that order.

fn parse_comma_sep<T>( &self, p: fn(_: ParseStream<'_>) -> Result<T>, ) -> Result<Vec<T>>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementations on Foreign Types

impl<'a> ParseBufferExt<'a> for ParseBuffer<'a>

fn look_and_eat<T: Eat>(&self, token: T, lookahead: &Lookahead1<'a>) -> bool

Consumes a token T if present, looking it up using the provided Lookahead1 instance.

fn eat<T: Eat>(&self, t: T) -> bool

fn eat2<T1: Eat, T2: Eat>(&self, t1: T1, t2: T2) -> bool

fn eat3<T1: Eat, T2: Eat, T3: Eat>(&self, t1: T1, t2: T2, t3: T3) -> bool

fn parse_comma_sep<T>( &self, p: fn(_: ParseStream<'_>) -> Result<T>, ) -> Result<Vec<T>>
