Version 0.2.0

What's New in v0.2.0

This release adds comprehensive type utilities for type manipulation.

New Type Utilities

• KeyOf[T] - Returns all member names as a tuple of Literal types

  • Similar to TypeScript's keyof operator
  • Example: KeyOf[User] returns tuple[Literal["name"], Literal["age"]]

• *Template[Parts] - Template literal string builder

  • Concatenates string literal types at runtime
  • Example: Template["api/v1/", Literal["users"]] returns Literal["api/v1/users"]

• DeepPartial[T] - Make all fields recursively optional

  • Applies optional transformation to all nested types
  • Example: DeepPartial[User] makes all nested fields optional

• Partial[T] - Make all fields optional (non-recursive)

  • Makes all top-level fields optional without recursion
  • Example: Partial[User] returns name: str | None, age: int | None

• Required[T] - Remove Optional from all fields

  • Inverse operation of Partial
  • Example: Required[OptionalUser] removes | None from all fields

• Pick[T, K] - Pick specific fields from a type

  • Creates a new type with only the specified fields
  • Example: Pick[User, tuple["name", "email"]]

• Omit[T, K] - Omit specific fields from a type

  • Creates a new type excluding specified fields
  • Example: Omit[User, tuple["password"]]
