ReplaceKeys

Implement a type ReplaceKeys, that replace keys in union types, if some type has not this key, just skip replacing, A type takes three arguments.

For example:

type NodeA = { type: 'A' name: string flag: number } type NodeB = { type: 'B' id: number flag: number } type NodeC = { type: 'C' name: string flag: number } type Nodes = NodeA | NodeB | NodeC type ReplacedNodes = ReplaceKeys<Nodes, 'name' | 'flag', {name: number, flag: string}> // {type: 'A', name: number, flag: string} | {type: 'B', id: number, flag: string} | {type: 'C', name: number, flag: string} // would replace name from string to number, replace flag from number to string. type ReplacedNotExistKeys = ReplaceKeys<Nodes, 'name', {aa: number}> // {type: 'A', name: never, flag: number} | NodeB | {type: 'C', name: never, flag: number} // would replace name to never
