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"
