Struct Target 

pub struct Target(/* private fields */);

A parsed error declaration before semantic validation.

Implementations

impl Target

pub fn input(input: &DeriveInput) -> Result<Self>

Parse an error target from a derive input.

pub fn validate(self) -> Result<ValidatedTarget>

Validate the parsed declaration and return proof-bearing semantics.

Errors

Returns a diagnostic when declarations conflict or field references do not satisfy their semantic requirements.
