Enum combine::error::ParseResult
source · [−]pub enum ParseResult<T, E> {
CommitOk(T),
PeekOk(T),
CommitErr(E),
PeekErr(Tracked<E>),
}
Expand description
A Result
type which has the committed status flattened into the result.
Conversions to and from std::result::Result
can be done using result.into()
or
From::from(result)
Variants
CommitOk(T)
The parser has succeeded and has committed to this parse. If a parser after this fails,
other parser alternatives will not be attempted (CommitErr
will be returned)
PeekOk(T)
The parser has succeeded and has not committed to this parse. If a parser after this fails,
other parser alternatives will be attempted (PeekErr
will be returned)
CommitErr(E)
The parser failed other parse alternatives will not be attempted.
PeekErr(Tracked<E>)
The parser failed but other parse alternatives may be attempted.
