libero/codegen_decoders

Typed decoder generators.

Emits JS decoder source from discovered types and handler endpoints. Returns strings; writing to disk is the consumer’s responsibility.

Values

emit_class_statics

</>

pub fn emit_class_statics(
  discovered: List(walker.DiscoveredType),
) -> String

Emit per-variant class-static assignments for every discovered user type. __wireAtom carries the 10-char hash; __fieldTypes carries the positional field-type hints the encoder needs (Float marked, containers wrapped, primitives null). These statics replace the runtime _bareToQualifiedAtom and fieldTypeRegistry lookup tables.

Even 0-arity variants get a __fieldTypes = [] for symmetry; the encoder branches on key count so the empty array is never indexed.

emit_client_msg_statics

</>

pub fn emit_client_msg_statics(
  endpoints endpoints: List(scanner.HandlerEndpoint),
  dispatch_module_ref dispatch_module_ref: String,
) -> String

emit_typed_decoders

</>

pub fn emit_typed_decoders(
  discovered: List(walker.DiscoveredType),
) -> String

Emit a JS string with one decoder function per discovered type, registration calls that populate etf/wire_ffi.mjs’s typed decoder registry, and an ensure_decoders entry point.

generate_decoders_ffi

</>

pub fn generate_decoders_ffi(
  discovered discovered: List(walker.DiscoveredType),
  endpoints endpoints: List(scanner.HandlerEndpoint),
  relpath_prefix relpath_prefix: String,
  package package: String,
  dispatch_module dispatch_module: option.Option(String),
) -> String

Generate the JS FFI decoder source from discovered types and endpoints.

generate_decoders_gleam

</>

pub fn generate_decoders_gleam(
  ffi_module_path ffi_module_path: String,
) -> String

Generate the Gleam wrapper module source for the typed decoder FFI.
