pub fn consume<'a, I: 'a, O: 'a>() -> ConduitM<'a, I, O, Option<I>>
Wait for an input chunk from upstream.
If no data is available, returns None.
Once it returns None, subsequent calls will also return None.
Prefix searches with a type followed by a colon (e.g.
fn:) to restrict the search to a given type.
Accepted types are: fn, mod,
struct, enum,
trait, typedef (or
tdef).
Search functions by type signature (e.g.
vec -> usize)
