}Expand description
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.
Provided Methods§
fn parse_body(self, body: &Data) -> Result<Self>
sourcefn parse_variant(&mut self, variant: &Variant) -> Result<()>
fn parse_variant(&mut self, variant: &Variant) -> Result<()>
Apply the next found variant to the object, returning an error if parsing goes wrong.
sourcefn parse_field(&mut self, field: &Field) -> Result<()>
fn parse_field(&mut self, field: &Field) -> Result<()>
Apply the next found struct field to the object, returning an error if parsing goes wrong.
sourcefn validate_body(&self, errors: &mut Accumulator)
fn validate_body(&self, errors: &mut Accumulator)
Perform validation checks that require data from more than one field or variant. The default implementation does no validations. Implementors can override this method as appropriate for their use-case.
Object Safety§
This trait is not object safe.
