Struct FunctionsConfig 

pub struct FunctionsConfig {
    pub module_dir: PathBuf,
    pub definitions: Vec<FunctionDefinition>,
    pub dlq_store: Option<String>,
}

The compiled schema’s "functions" section — the whole of what an author declares about functions, and the single definition of that shape.

It is a sibling of the core CompiledSchema in schema.compiled.json, not a field of it: fraiseql-core knows nothing about functions, and the dependency runs the other way (fraiseql-functions optionally uses core, never the reverse). The server reads it through ExtendedCompiledSchema; the CLI writes it there and reads it back in fraiseql functions invoke.

{
  "functions": {
    "module_dir": "functions",
    "definitions": [
      { "name": "on_create_user", "trigger": "after:mutation:createUser", "runtime": "Wasm" }
    ]
  }
}

One definition, deliberately

This shape used to exist three times: fraiseql-server’s FunctionsConfig, the CLI harness’s private FunctionsSection (“a local mirror … so the harness does not pull the whole server crate in”), and — had #1325 followed the same instinct — an authoring mirror in IntermediateSchema. Three copies of a rule lose the fourth. It lives here, in the crate that owns FunctionDefinition, so the producer and both consumers deserialize the same struct.

Fields

module_dir: PathBuf

Directory containing the function modules (.wasm, .js, .ts), resolved relative to the server’s working directory.

Required on the wire. The authoring default (functions/) lives in the compiler, which always emits an explicit value — so a hand-written compiled schema that omits it still fails loudly rather than silently resolving somewhere the author did not choose.

definitions: Vec<FunctionDefinition>

The declared functions.

dlq_store: Option<String>

Which dead-letter store backs function dispatch (#598): "memory" (the default — dead-letters vanish on restart) or "postgres" (durable, survives a restart; requires a database pool). Overridable by the FRAISEQL_FUNCTIONS_DLQ_STORE env var. Absent ⇒ memory.
