Struct tidb_query_codegen::rpn_function::RpnFnSignatureParam[−][src]

struct RpnFnSignatureParam {
    _pat: Pat,
    has_option: bool,
    eval_type: RpnFnRefEvaluableType,
}

Parses a function signature parameter like val: &Option<T> or val: &T. If input has &Option, set has_option to true; otherwise, set has_option to false. Caller can use has_option to check if input is valid.

Fields

_pat: Pathas_option: booleval_type: RpnFnRefEvaluableType
