Enum fungui_syntax::Info

pub enum Info<T, R> {
    Token(T),
    Range(R),
    Owned(String),
    Borrowed(&'static str),
}

Enum holding error information. Variants are defined for Stream::Item and Stream::Range as well as string variants holding easy descriptions.

As there is implementations of From for String and &'static str the constructor need not be used directly as calling msg.into() should turn a message into the correct Info variant.

Variants

Token(T)Range(R)Owned(String)Borrowed(&'static str)
