Module attributes 

Parsing helpers for procedural-macro attribute arguments.

Structs

Args

A parsed set of macro attribute arguments, keyed by argument name.

IdentWraper

A newtype wrapper around an identifier that implements Parse to consume an identifier from the input stream regardless of keyword status.

Enums

AssignmentValue

A value appearing on the right-hand side of an = assignment.

EvaluationValue

A value appearing in evaluation position, e.g. inside a delimited group.

Item

A single lexical item encountered while parsing attribute arguments.

Value

The value associated with an argument, distinguishing values parsed in evaluation position from those parsed on the right-hand side of an =.

Functions

get_attributes

Parses the contents of the given attribute into Args, returning None if the attribute arguments fail to parse.
