Struct mz_sql::plan::side_effecting_func::SideEffectingFuncImpl

pub struct SideEffectingFuncImpl {
    pub name: &'static str,
    pub oid: u32,
    pub param_types: &'static [ScalarType],
    pub return_type: ColumnType,
    pub plan_fn: fn(_: &[Datum<'_>]) -> SideEffectingFunc,
}

Defines the implementation of a side-effecting function.

This is a very restricted subset of the Func struct (no overloads, no variadic arguments, etc) to make side-effecting functions easier to plan.

Fields

name: &'static str

The name of the function.

oid: u32

The OID of the function.

param_types: &'static [ScalarType]

The parameter types for the function.

return_type: ColumnType

The return type of the function.

plan_fn: fn(_: &[Datum<'_>]) -> SideEffectingFunc

A function that will produce a SideEffectingFunc given arguments that have been evaluated to Datums.
