Module: Channel

Channel.filterMap

Filters and maps output elements using a Filter.

When to use

Use to keep only channel output elements accepted by a Filter and emit each filter success value.

Details

Successful filter results are emitted as mapped values. Failed filter results are discarded. The source channel’s errors and done value are preserved.

See

• filter for keeping original output elements with a predicate
• filterMapEffect for using an effectful Filter
• filterMapArray for filtering arrays of output elements
