Package: effect
Module: Channel

Channel.catchCauseIf

Catches causes of failure that match a specific filter, allowing conditional error recovery based on the type of failure.

When to use

Use to recover a channel only when its full Cause satisfies a boolean predicate.

Details

When the predicate matches, the recovery function receives the original cause. When it does not match, the returned channel fails with the original cause.

See

• catchCauseFilter for selecting causes with a Filter
• catchCause for recovering from every cause
• catchIf for recovering from typed channel errors

Signature

declare const catchCauseIf: { <OutErr, OutElem1, OutErr1, OutDone1, InElem1, InErr1, InDone1, Env1>(predicate: Predicate.Predicate<Cause.Cause<OutErr>>, f: (cause: Cause.Cause<OutErr>) => Channel<OutElem1, OutErr1, OutDone1, InElem1, InErr1, InDone1, Env1>): <OutElem, OutDone, InElem, InErr, InDone, Env>(self: Channel<OutElem, OutErr, OutDone, InElem, InErr, InDone, Env>) => Channel<OutElem | OutElem1, OutErr | OutErr1, OutDone | OutDone1, InElem & InElem1, InErr & InErr1, InDone & InDone1, Env | Env1>; <OutElem, OutErr, OutDone, InElem, InErr, InDone, Env, OutElem1, OutErr1, OutDone1, InElem1, InErr1, InDone1, Env1>(self: Channel<OutElem, OutErr, OutDone, InElem, InErr, InDone, Env>, predicate: Predicate.Predicate<Cause.Cause<OutErr>>, f: (cause: Cause.Cause<OutErr>) => Channel<OutElem1, OutErr1, OutDone1, InElem1, InErr1, InDone1, Env1>): Channel<OutElem | OutElem1, OutErr | OutErr1, OutDone | OutDone1, InElem & InElem1, InErr & InErr1, InDone & InDone1, Env | Env1>; }
