Required Methods§

source

fn custom_value_kind_matches_type_kind( schema: &SchemaV1<Self::CustomSchema>, custom_value_kind: Self::CustomValueKind, type_kind: &TypeKind<<Self::CustomSchema as CustomSchema>::CustomTypeKind<LocalTypeId>, LocalTypeId> ) -> bool

Used in the typed traverser

This method is only called if the type_kind is not “Any”

source

fn custom_type_kind_matches_non_custom_value_kind( schema: &SchemaV1<Self::CustomSchema>, custom_type_kind: &<Self::CustomSchema as CustomSchema>::CustomTypeKind<LocalTypeId>, non_custom_value_kind: ValueKind<Self::CustomValueKind> ) -> bool

Used in the typed traverser

This method is only called if custom_value_kind_matches_type_kind didn’t apply. It’s a fallback for any custom type kinds which should match against non-custom value kinds (in most cases there won’t be any such cases).

Object Safety§

This trait is not object safe.
