MethodNames

This utility type takes an Api interface as type argument and returns a union type of all the property names whose values are functions.

Example:

import type { MethodNames } from "tsafe";

type T = {
	x: number;
	y: number;
	method1(): void;
	method2(): void;
};

type TMethodNames = MethodNames<T>;

//resulting type is: "method1" | "method2"

The result will be the same if one or more of the methods are optional.

import type { MethodNames } from "tsafe";

type T = {
	x: number;
	y: number;
	method1(): void;
	method2?(): void;
};

type TMethodNames = MethodNames<T>;

//resulting type is: "method1" | "method2"
