\n \n \n Standard Schema
\n
\n A family of specs for interoperable TypeScript\n \n standardschema.dev\n
\n \n\n\n\nThe Standard Schema project is a set of interfaces that standardize the provision and consumption of shared functionality in the TypeScript ecosystem.\n\nIts goal is to allow tools to accept a single input that includes all the types and capabilities they need— no library-specific adapters, no extra dependencies. The result is an ecosystem that's fair for implementers, friendly for consumers, and open for end users.\n\n## The specifications\n\nThe specifications can be found below in their entirety. Libraries wishing to implement a spec can copy/paste the code block below into their codebase. They're also available at `@standard-schema/spec` on [npm](https://www.npmjs.com/package/@standard-schema/spec) and [JSR](https://jsr.io/@standard-schema/spec).\n\n```ts\n// #########################\n// ### Standard Typed ###\n// #########################\n\n/** The Standard Typed interface.
