Module darling::util

Utility types for attribute parsing.

Structs

Flag	Marker type equivalent to Option<()> for use in attribute parsing.
IdentList	A list of syn::Ident instances. This type is used to extract a list of words from an attribute.
IdentString	A wrapper for an Ident which also keeps the value as a string.
Ignored	An efficient way of discarding data from a syntax element.
SpannedValue	A value and an associated position in source code. The main use case for this is to preserve position information to emit warnings from proc macros. You can use a SpannedValue<T> as a field in any struct that implements or derives any of darling's core traits.
WithOriginal	A container to parse some syntax and retain access to the original.

Enums

Override

A value which can inherit a default value or have an explicit value specified.
