CodeRuntime (abstract seam) — provided by @deepseek-ai/dsh-code-runtime.
Registers one ctx.codeRuntime implementation. Program, budget, abort, and substrate failures resolve in CodeRunResult; only seam misuse rejects. Implementations bridge structured-cloneable bindings while treating programs as hostile peers, isolate runs from one another, and terminate and await in-flight runs during disposal.
abstract readonly language: string
The source language run expects program to be written in, as a lowercase identifier. Informational, not gating — a consumer that generates language-specific presentation (typed SDK stubs, usage instructions) switches on it and fails loud on a language it cannot present. Well-known value: 'typescript'.
abstract readonly isolation: string
The execution substrate, as a lowercase identifier. Informational, not gating — a descriptor so deployments and diagnostics can tell backends apart, not a security claim. Well-known values: 'worker-thread', 'process', 'container'.
abstract run(request: CodeRunRequest): Promise<CodeRunResult>
Execute one program against the request's bindings and capture what it emitted. See the class doc for the resolution contract (error is a result field; rejection means seam misuse only).
request — the program, its bindings, and the abort signal; the request carries everything the runtime acts on, with no hidden defaults.Returns the run's outcome: completion value (when transferable), the ordered log capture, and the failure (if any).
