Struct DoCatchBuilder 

pub struct DoCatchBuilder { /* private fields */ }

Builder for a .do_catch_exception() / .do_catch_when() / .do_catch_all() clause.

Implementations

impl DoCatchBuilder

pub fn process(self, processor: BoxProcessor) -> Self

Add a step to the catch clause’s sub-pipeline.

pub fn on_when(self, predicate: FilterPredicate) -> Self

Set an additional predicate that must also match for this catch clause to fire.

pub fn handled(self) -> Self

Mark this catch clause as handled: the caught error is absorbed and the clause’s exchange becomes the final result (no re-throw).

Only Handled and Propagate are supported. There is intentionally no general disposition(value) setter, so Continued is unrepresentable at the type level.

Valid use (compiles):

let _ = RouteBuilder::from("direct:start").route_id("x").do_try()
    .do_catch_exception(&["E"])
    .handled();

Rejected — does not compile (no disposition method exists):

let b = RouteBuilder::from("direct:start").route_id("x").do_try()
    .do_catch_exception(&["E"]);
b.disposition(ExceptionDisposition::Continued);

pub fn propagate(self) -> Self

Mark this catch clause as propagating: the clause runs for side-effects and the original error is re-thrown.

Only Handled and Propagate are supported. There is intentionally no general disposition(value) setter, so Continued is unrepresentable at the type level (semantically ambiguous at catch-clause scope; .continued() is deliberately not provided).

pub fn end_do_catch(self) -> DoTryBuilder

Close the catch clause and return the parent DoTryBuilder.
