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.

Required methods

fn unexpected_token(token: Item) -> Self

fn unexpected_range(token: Range) -> Self

fn unexpected_message<T>(msg: T) -> Self where
    T: Display, 

fn expected_token(token: Item) -> Self

fn expected_range(token: Range) -> Self

fn expected_message<T>(msg: T) -> Self where
    T: Display, 

fn message_token(token: Item) -> Self

fn message_range(token: Range) -> Self

fn message_message<T>(msg: T) -> Self where
    T: Display, 

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.
