ParseBuffer extensions

Required Methods

fn parse_bool_attr(&self) -> Result<bool, Error>

Parse a boolean attribute

Value	Result
my_attr	true
my_attr(true)	true
my_attr(false)	false
my_attr = true	true
my_attr = false	false

fn parse_valued_attr<P>(&self) -> Result<P, Error>where P: Parse,

Parse a valued attribute

Value	Result
my_attr(something)	P::parse(something)
my_attr = something	P::parse(something)

The my_attr(something) syntax should be preferred as my_attr = something can’t always deserialise some types (e.g. Visibility)

fn iter_delimited<T, D>(&self) -> DelimitedIter<'_, T, D> where T: Parse, D: Parse,

Shortcut for DelimitedIter::new

Object Safety

This trait is not object safe.
