}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.
Required methods
fn unexpected_token(token: Item) -> Self
fn unexpected_range(token: Range) -> Self
fn unexpected_format<T>(msg: T) -> Self where
T: Display,
fn expected_token(token: Item) -> Self
fn expected_range(token: Range) -> Self
fn expected_format<T>(msg: T) -> Self where
T: Display,
fn message_token(token: Item) -> Self
fn message_range(token: Range) -> Self
fn message_format<T>(msg: T) -> Self where
T: Display,
fn is_unexpected_end_of_input(&self) -> bool
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.
