Struct FnRegistry 

pub struct FnRegistry { /* private fields */ }

Registry of all TypeScript functions available to the runtime.

Populated at startup when the Bun process reports its registered functions. Used by the router to validate function calls and by Studio to show available functions.

Implementations

impl FnRegistry

pub fn new() -> Self

pub fn register(&self, def: FnDef)

Register a function. Called during startup handshake with the Bun process.

pub fn register_all(&self, defs: Vec<FnDef>)

Register multiple functions at once (from startup handshake).

pub fn replace_all(&self, defs: Vec<FnDef>)

Atomically replace the entire registered set. Used after the runtime supervisor respawns Bun: any function that was deleted between processes must stop being callable, and register_all() alone won’t remove stale entries.

pub fn get(&self, name: &str) -> Option<FnDef>

Look up a function by name.

pub fn list(&self) -> Vec<FnDef>

List all registered functions.

pub fn list_by_type(&self, fn_type: FnType) -> Vec<FnDef>

List functions of a specific type.

pub fn exists(&self, name: &str) -> bool

Check if a function is registered.

pub fn count(&self) -> usize

Number of registered functions.

Trait Implementations

impl Default for FnRegistry
