Module darling::util[−][src]

Utility types for attribute parsing.

Structs

Flag	Marker type equivalent to `Option<()>` for use in attribute parsing.
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.
PathList	A list of `syn::Path` instances. This type is used to extract a list of paths from an attribute.
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.

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