Struct TraitBridgeSpec 

pub struct TraitBridgeSpec<'a> {
    pub trait_def: &'a TypeDef,
    pub bridge_config: &'a TraitBridgeConfig,
    pub core_import: &'a str,
    pub wrapper_prefix: &'a str,
    pub type_paths: HashMap<String, String>,
    pub error_type: String,
    pub error_constructor: String,
}

Everything needed to generate a trait bridge for one trait.

Fields

trait_def: &'a TypeDef

The trait definition from the IR.

bridge_config: &'a TraitBridgeConfig

Bridge configuration from alef.toml.

core_import: &'a str

Core crate import path (e.g., "kreuzberg").

wrapper_prefix: &'a str

Language-specific prefix for the wrapper type (e.g., "Python", "Js", "Wasm").

type_paths: HashMap<String, String>

Map of type name → fully-qualified Rust path for qualifying Named types.

error_type: String

The crate’s error type name (e.g., "KreuzbergError"). Defaults to "Error".

error_constructor: String

Error constructor pattern. {msg} is replaced with the message expression.

Implementations

impl<'a> TraitBridgeSpec<'a>

pub fn error_path(&self) -> String

Fully qualified error type path (e.g., "kreuzberg::KreuzbergError").

pub fn make_error(&self, msg_expr: &str) -> String

Generate an error construction expression from a message expression.

pub fn wrapper_name(&self) -> String

Wrapper struct name: {prefix}{TraitName}Bridge (e.g., PythonOcrBackendBridge).

pub fn trait_snake(&self) -> String

Snake-case version of the trait name (e.g., "ocr_backend").

pub fn trait_path(&self) -> String

Full Rust path to the trait (e.g., kreuzberg::OcrBackend).

pub fn required_methods(&self) -> Vec<&'a MethodDef>

Methods that are required (no default impl) — must be provided by the foreign object.

pub fn optional_methods(&self) -> Vec<&'a MethodDef>

Methods that have a default impl — optional on the foreign object.
