Implementations

impl<R: KindRepr> Config<R>

pub fn validate_reprs(&self, input: &DeriveInput) -> Result<Vec<R>, Vec<Error>>

Validate that input’s representation attributes conform to the requirements specified by this Config.

validate_reprs extracts the repr attributes, validates that they conform to the requirements of self, and returns them. Regardless of whether align attributes are considered during validation, they are stripped out of the returned value since no callers care about them.
