Struct TypesRef

pub struct TypesRef<'a> { /* private fields */ }

Represents the types known to a crate::Validator during validation.

Retrieved via the crate::Validator::types method.

Implementations

impl<'a> TypesRef<'a>

pub fn id(&self) -> ValidatorId

Get the id of the validator that these types are associated with.

pub fn get<T>(&self, id: T) -> Option<&'a <T as TypeIdentifier>::Data>

Gets a type based on its type id.

Returns None if the type id is unknown.
