Struct ZigTraitBridgeGenerator 

pub struct ZigTraitBridgeGenerator {
    pub prefix: String,
}

Zig-specific TraitBridgeGenerator implementation.

Carries the FFI symbol prefix (e.g., "kreuzberg") used when deriving the C symbol for unregister_* and clear_* wrappers.

The required trait methods that produce Rust source (gen_sync_method_body, gen_async_method_body, gen_constructor, gen_registration_fn) return empty strings because Zig bridge code is produced by the standalone [emit_trait_bridge] free function, not the shared driver.

Fields

prefix: String

FFI symbol prefix (e.g., "kreuzberg").

Implementations

impl ZigTraitBridgeGenerator

pub fn new(prefix: impl Into<String>) -> Self

Construct a new generator for the given FFI symbol prefix.

Trait Implementations

impl TraitBridgeGenerator for ZigTraitBridgeGenerator

fn gen_unregistration_fn(&self, spec: &TraitBridgeSpec<'_>) -> String

Emit a Zig wrapper that calls c.{prefix}_{unregister_fn}(name, out_error).

Returns an empty string when spec.bridge_config.unregister_fn is None.

fn gen_clear_fn(&self, spec: &TraitBridgeSpec<'_>) -> String

Emit a Zig wrapper that calls c.{prefix}_{clear_fn}(out_error).

Returns an empty string when spec.bridge_config.clear_fn is None.

fn foreign_object_type(&self) -> &str

The type of the wrapped foreign object (e.g., "Py<PyAny>", "ThreadsafeFunction").

fn bridge_imports(&self) -> Vec<String>

Additional use imports needed for the bridge code.

fn gen_sync_method_body( &self, _method: &MethodDef, _spec: &TraitBridgeSpec<'_>, ) -> String

Generate the body of a synchronous method bridge.

fn gen_async_method_body( &self, _method: &MethodDef, _spec: &TraitBridgeSpec<'_>, ) -> String

Generate the body of an async method bridge.

fn gen_constructor(&self, _spec: &TraitBridgeSpec<'_>) -> String

Generate the constructor body that validates and wraps the foreign object.

fn gen_registration_fn(&self, _spec: &TraitBridgeSpec<'_>) -> String

Generate the complete registration function including attributes, signature, and body.

fn async_trait_is_send(&self) -> bool

Whether the #[async_trait] macro should require Send on its futures.
