Expand description

Parse from a TokenBuf.

Required Methods§

fn parse(buf: &mut &TokenBuf<T>) -> Result<Self, Error<T::Span>>

Parse a value from a TokenBuf.

The referenced &TokenBuf will be modified to point past the parsed tokens on success.

Provided Methods§

fn parse_all(buf: &mut &TokenBuf<T>) -> Result<Self, Error<T::Span>>

Parse a value from a TokenBuf buffer, but return an error if there’s any tokens left in the buffer after parsing.

The referenced &TokenBuf will be modified to point past the parsed tokens on success. If parsing succeeds but there are tokens left in the buffer, the buffer will point to the left over tokens.

Object Safety§

This trait is not object safe.
