Struct CallHandler 

pub struct CallHandler<'a, T = BootResponse> { /* private fields */ }

Reusable access to the next handler in an interceptor chain.

This is the Rust equivalent of Nest’s CallHandler. Calling handle runs the remaining interceptors, pipes, validation, and handler. The handle is reusable so an interceptor can deliberately retry the downstream pipeline sequentially. Concurrent calls are rejected because they would share one request-scoped provider context.

Implementations

impl<'a, T> CallHandler<'a, T>

where T: Send + 'a,

pub fn from_fn<F, Fut>(call: F) -> Self

where F: Fn() -> Fut + Send + Sync + 'a, Fut: Future<Output = Result<T>> + Send + 'a,

Build a call handler from a reusable async function.

Frameworks normally provide the handler to an interceptor. This constructor is public so interceptors and combinators can be tested in isolation.

pub fn handle(&self) -> BoxFuture<'a, Result<T>>

Run the remaining interceptor chain and underlying handler once.

A completed or cancelled call releases the handler for a later retry. Starting overlapping calls returns BootError::Internal.

Trait Implementations

impl<'a, T> Clone for CallHandler<'a, T>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.
