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 disposition(self, value: ExceptionDisposition) -> Self

Set the disposition for this catch clause.

Panics

Panics if value is ExceptionDisposition::Continued, which is not supported in doTry MVP (spec §3).

pub fn handled(self) -> Self

Sugar for disposition(ExceptionDisposition::Handled).

The caught error is marked handled and the catch clause’s exchange becomes the final result (no re-throw).

pub fn propagate(self) -> Self

Sugar for disposition(ExceptionDisposition::Propagate).

The catch clause runs for side-effects and the original error is re-thrown.

Note: .continued() is intentionally NOT provided — Continued is rejected at parse time for doTry MVP per spec §3 (semantically ambiguous at catch-clause scope).

pub fn end_do_catch(self) -> DoTryBuilder

Close the catch clause and return the parent DoTryBuilder.
