Implement sequence sender a... | NVIDIA/stdexec

Nobody has claimed this yet.

Start by reviewing the existing contents of exec/ and the sequence sender APIs. The issue lists many unchecked sources, sinks, adaptors, and queries but names no specific entry point or tests, so select and scope one algorithm before implementation. Done is not defined for the full checklist.

Written by the indexing model from the issue text.

Here is a list of sequence sender algorithms and types that could be included into exec/

Types

any_sequence_of

Sinks

ignore_all(sequence) -> sender
Returns a sender that completes when the input sequence completes. If an element of the sequence completes with an set_error_t(E) or set_stopped_t() a stop request will be issued and the signal will be forwarded.
first_value(sequence) -> sender
last_value(sequence) -> sender
reduce

Sources

empty_sequence() -> sequence
sender -> sequence
repeat(sender) -> sequence
generate_each(fn) -> sequence
iterate(range) -> sequence

Adaptors

merge_all(sequences, ...) -> sequence, merge_all_sequence(sequence) -> sequence
filter_each(sequence, predicate) -> sequence
take_while(sequence, predicate) -> sequence
transform_each(sequence, adaptor) -> sequence
zip(sequences, ...) -> sequence
scan

Queries
