Struct FunctionParam 

pub struct FunctionParam {
    pub name: String,
    pub type_name: String,
    pub type_reference: Option<RoutineColumnTypeReference>,
    pub written_type: Option<String>,
    pub mode: FunctionParamMode,
    pub default: Option<Expr>,
    pub default_type: Option<RoutineDefaultType>,
}

One declared parameter of a user-defined function or procedure.

Fields

name: String

Parameter name. Empty for unnamed parameters (f(integer)), which are only addressable as $n.

type_name: String

Raw type name as written (last segment, lower-cased by the compiler; e.g. int4, text, numeric).

type_reference: Option<RoutineColumnTypeReference>

Parsed relation and column identity for %TYPE; ordinary types have no reference.

written_type: Option<String>

The type as the statement wrote it, as TypeNameToString spells it, which names a missing type until registration resolves the type.

mode: FunctionParamMode

default: Option<Expr>

DEFAULT <expr> for trailing input parameters.

default_type: Option<RoutineDefaultType>

The analyzed default expression type, used when an omitted polymorphic input supplies call typing.
