import type { Merge } from "./merge.mjs";
/**
Override existing properties of the given type. Similar to `Merge`, but enforces that the original type has the properties you want to override.
This is useful when you want to override existing properties with a different type and make sure that these properties really exist in the original.
@example
```
type Foo = {
a: string
b: string
}
type Bar = OverrideProperties<Foo, {b: number}>
//=> {a: string, b: number}
type Baz = OverrideProperties<Foo, {c: number}>
// Error, type '{ c: number; }' does not satisfy the constraint '{ c: never; }'
type Fizz = OverrideProperties<Foo, {b: number; c: number}>
// Error, type '{ b: number; c: number; }' does not satisfy the constraint '{ b: number; c: never; }'
```
