Struct UserFieldTransform 

pub struct UserFieldTransform(/* private fields */);

A field callback. Undefined, null, and native object values remain distinct.

Implementations

impl UserFieldTransform

pub fn new( callback: impl Fn(Value) -> AuthResult<FieldValue> + Send + Sync + 'static, ) -> Self

Use a synchronous callback at public-input and adapter boundaries.

pub fn new_async<F, Fut>(callback: F) -> Self

where F: Fn(Value) -> Fut + Send + Sync + 'static, Fut: Future<Output = AuthResult<FieldValue>> + Send + 'static,

Await a callback at core, Organization, and supported plugin adapter boundaries. Synchronous public-input parsing rejects async callbacks.

pub async fn call(&self, value: Value) -> AuthResult<FieldValue>

Invoke a callback and await its result without changing its original error.

pub fn call_sync(&self, value: Value) -> AuthResult<FieldValue>

Invoke a callback at a synchronous policy boundary. Async callbacks return a configuration error before application work starts.

Trait Implementations

impl Clone for UserFieldTransform

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
