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

pub fn unexpected_token(token: Item) -> Self[src]

pub fn unexpected_range(token: Range) -> Self[src]

pub fn unexpected_format<T>(msg: T) -> Self where
    T: Display, [src]

pub fn expected_token(token: Item) -> Self[src]

pub fn expected_range(token: Range) -> Self[src]

pub fn expected_format<T>(msg: T) -> Self where
    T: Display, [src]

pub fn message_token(token: Item) -> Self[src]

pub fn message_range(token: Range) -> Self[src]

pub fn message_format<T>(msg: T) -> Self where
    T: Display, [src]

pub fn is_unexpected_end_of_input(&self) -> bool[src]

pub fn into_other<T>(self) -> T where
    T: StreamError<Item, Range>, [src]

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.
