v11.1.0

Today, we're happy to publish a small follow-up to v11.0.1!

This release fixes a nasty build failure when using the format feature.
Note: For those that use the format feature, this release bumps the MSRV to 1.88. We'd have preferred to do this in a major release, but felt this was acceptable since the build was broken by one of the dependencies anyway.

New features

TypeScript enums with #[ts(repr(enum))

#[ts(repr(enum)) instructs ts-rs to generate an enum, instead of a type for your rust enum.

#[derive(TS)]
#[ts(repr(enum))]
enum Role {
    User,
    Admin,
}
// will generate `export enum Role { "User", "Admin" }`

Discriminants are preserved, and you can use the variant's name as discriminant instead using #[ts(repr(enum = name))]

#[ts(optional_fields)] in enums

The #[ts(optional_fields)] attribute can now be applied directly to enums, or even to individual enum variants.

Control over file extensions in imports

Normally, we generate import { Type } from "file" statements. In some scenarios though, it might be necessary to use a .ts or even .js extension instead.
This is now possible by setting the TS_RS_IMPORT_EXTENSION environment variable.

Note: With the introduction of this feature, we deprecate the import-esm cargo feature. It will be removed in a future major release.
