shape 🔒

Types for “shape” validation. This allows types deriving FromDeriveInput etc. to declare that they only work on - for example - structs with named fields, or newtype enum variants.

Enums

DefaultExpression

A default/fallback expression encountered in attributes during parsing.

Traits

ParseAttribute

Middleware for extracting attribute values. Implementers are expected to override parse_nested so they can apply individual items to themselves, while parse_attributes is responsible for looping through distinct outer attributes and collecting errors.

ParseData

Middleware for extracting values from the body of the derive input. Implementers are expected to override parse_field or parse_variant as appropriate for their use-case, while parse_body dispatches to the appropriate methods and handles error collection.
