gleam_handlers

Gleam handler-stub generator for AsyncAPI.

Emits one handler-stub function per receive operation, grouped by channel. receive operations (messages arriving from the client) become handle_* stubs. send operations are the server’s outgoing messages — encode those with the send_* functions in the generated server module, not here — so they contribute nothing to this file. Payload types are referenced by name; generate them with nori’s Gleam type generator from the same schemas.

Values

generate

</>

pub fn generate(
  spec: ir.AsyncCodegenIR,
  types_module: String,
) -> String

Generate a .gleam handler-stub module from the IR.

types_module is the import path of the companion types module produced by generate_gleam_types (e.g. "generated/types"); named payload types are referenced through its types alias.

has_handlers

</>

pub fn has_handlers(spec: ir.AsyncCodegenIR) -> Bool

Whether this spec produces any handler stubs. False for a send-only spec, in which case handlers.gleam would be an empty module and should not be written at all (an empty module warns on gleam build).
