Package: effect
Module: Channel

Channel.filterMapEffect

Filters and maps output elements using an effectful Filter.

When to use

Use to apply effectful logic that can discard channel output elements and emit transformed values for the elements that pass.

Details

Successful filter results are emitted as mapped values. Failed filter results are discarded. Failures from the effectful filter fail the returned channel.

See

• filterMap for using a synchronous Filter
• filterEffect for effectfully keeping original output elements
• mapEffect for effectfully transforming every output element
• filterMapArrayEffect for effectful filtering of array outputs

Signature

declare const filterMapEffect: { <OutElem, B, X, EX, RX>(filter: Filter.FilterEffect<OutElem, B, X, EX, RX>): <OutErr, OutDone, InElem, InErr, InDone, Env>(self: Channel<OutElem, OutErr, OutDone, InElem, InErr, InDone, Env>) => Channel<B, OutErr | EX, OutDone, InElem, InErr, InDone, Env | RX>; <OutElem, OutErr, OutDone, InElem, InErr, InDone, Env, B, X, EX, RX>(self: Channel<OutElem, OutErr, OutDone, InElem, InErr, InDone, Env>, filter: Filter.FilterEffect<OutElem, B, X, EX, RX>): Channel<B, OutErr | EX, OutDone, InElem, InErr, InDone, Env | RX>; }
