Open raaymax opened 1 month ago

raaymax commented 1 month ago

current:

interface AsyncIterable<T> {
    [Symbol.asyncIterator](): AsyncIterator<T>;
}

expected type:

interface AsyncIterable<T, TReturn = any, TNext = undefined> {
    [Symbol.asyncIterator](): AsyncIterator<T, TReturn, TNext>;
}

version:

deno 1.45.5 (release, aarch64-apple-darwin)
v8 12.7.224.13
typescript 5.5.2

I guess we need to wait for typescript 5.6 https://github.com/microsoft/TypeScript/blob/b4732bdd6199ec353ec0873f334515f391d80d3b/src/lib/es2018.asynciterable.d.ts#L19-L21
