Enum tidb_query_codegen::rpn_function::RpnFnRefEvaluableType[−][src]

[−]
enum RpnFnRefEvaluableType {
    Type(TypePath),
    Ref(TypePath),
}
[−]

Parses an evaluable type like &T, JsonRef or BytesRef. &T corresponds to Ref. JsonRef corresponds to Type.

Variants

Type(TypePath)
Ref(TypePath)

Implementations

impl RpnFnRefEvaluableType[src][−]

fn parse_type_path(input: ParseStream<'_>) -> Result<Self>[src][−]

Parse type like JsonRef

fn parse_type_ref(input: ParseStream<'_>) -> Result<Self>[src][−]

Parse type like &T

fn get_type_path(&self) -> TypePath[src][−]

Transform new JsonRef-like style type to old &Json type.

Note: this is a workaround for current copr framework. After full migration, this function should be deprecated.

fn get_type_with_lifetime(&self, lifetime: TokenStream) -> TokenStream[src][−]

Add lifetime to current type. JsonRef -> JsonRef<'arg_> Int->&’arg_ Int`
