Module source 

The Source trait and built-in source adapters.

A source produces items one at a time via Source::pull. The driver pulls until Ok(None), then invokes Source::close before flushing downstream stages.

Structs

ChannelSourcestd

Source adapter over an std::sync::mpsc::Receiver.

FnSource

Source adapter over a closure that produces fallible items.

IterSource

Source adapter over any IntoIterator.

ReaderSourcestd

Line-buffered Source over any std::io::Read. Each pull returns one line (without the trailing newline).

Enums

Infallible

An error type that no IterSource ever returns.

Traits

Source

Producer at the head of a pipeline.
