Configuration for a single adapter.

Fields

name: String

pattern: AdapterPattern

core_path: String

Full Rust path to the core function/method (e.g., “html_to_markdown_rs::convert”)

params: Vec<AdapterParam>

Parameters

returns: Option<String>

Return type name

error_type: Option<String>

Error type name

owner_type: Option<String>

For async_method/streaming: the owning type name

item_type: Option<String>

For streaming: the item type

gil_release: bool

For Python: release GIL during call

trait_name: Option<String>

For callback_bridge: the Rust trait to implement (e.g., “MyHandler”)

trait_method: Option<String>

For callback_bridge: the trait method name (e.g., “handle”)

detect_async: bool

For callback_bridge: whether to detect async callbacks at construction time

request_type: Option<String>

For streaming (FFI backend): full Rust type path of the request payload deserialised from JSON (e.g. "my_crate::ChatCompletionRequest"). Required when generating FFI streaming bodies — codegen will hard-fail with a clear error if this field is absent on a streaming adapter.

skip_languages: Vec<String>

Language backends for which this adapter should NOT be emitted.

Mirrors the same field on [[crates.e2e.calls.*]]. Useful when a consumer’s core crate cannot compile on a given target (e.g. kreuzcrawl on wasm32-unknown-unknown which has no working async runtime for streaming). The adapter remains declared for every backend where it works, with explicit per-backend opt-out rather than removing the adapter entirely.

Values must match the canonical TOML language names used in languages ("python", "node", "wasm", "ruby", "php", "go", "java", "csharp", "elixir", "kotlin", "kotlin_android", "swift", "dart", "zig", "ffi", "r", "gleam", "c", "jni", "rust"). An unknown name fails at config-resolve time.

Example: skip_languages = ["wasm", "kotlin"]
