Expand description
StreamError
represents a single error returned from a Stream
or a Parser
.
Usually multiple instances of StreamError
is composed into a ParseError
to build the final
error value.

fn into_other<T>(self) -> T where
T: StreamError<Item, Range>,
fn into_other<T>(self) -> T where
T: StreamError<Item, Range>,
Converts self
into a different StreamError
type.
This should aim to preserve as much information as possible into the returned T
value but
if Self
ignores some information passed to it using one of the constructors that
information is naturally lost.
