[英]Typescript does not want to spread type that's object by exclusion
I'm having issues spreading an externally imported type that's an object
by way of Exclude
.我在通过Exclude
传播外部导入类型object
时遇到问题。 To demonstrate:展示:
const f = (): object => ({});
const v = {...f()}; // valid -> OK
const f = (): object | string => ({});
const v = {...f()}; // invalid -> OK
const f = (): Exclude<object | string, "string"> => ({});
const v = {...f()}; // invalid -> PROBLEM
In the last snippet I would expect the Exclude
to make the type valid.在最后一个片段中,我希望Exclude
使类型有效。 Is this me thinking about it wrongly, or is there another way of fixing this?这是我想错了,还是有另一种解决方法? (the type exemplified by object
is an external import I can't change). (以object
为例的类型是我无法更改的外部导入)。
You made a typo in the exclude
: You want to exclude the type string
not the type "string"
(which is a string
that can only have the value "string"
)您在exclude
中打错了:您要排除类型string
而不是类型 " string
"string"
(这是一个只能具有值"string"
的字符串)
const f = (): Exclude<object | string, string> => ({});
const v = { ...f2() }; // ok
