Enum IntError 

pub enum IntError {
    Floating,
    InvalidSuffix,
    InvalidOctalDigit,
    NoDigits,
    TooLarge,
}

Why a preprocessing number is not an integer constant.

IntError::Floating is not a diagnostic. It means the spelling belongs to the floating path, and it is an error here so that the caller cannot forget to ask.

Variants

Floating

This is a floating constant. Nothing is wrong with it.

InvalidSuffix

The characters after the digits are not a suffix.

InvalidOctalDigit

An 8 or a 9 in a constant that started with 0.

NoDigits

0x or 0b with no digits after it.

TooLarge

Larger than any integer type, or than the hundred and twenty eight bits the value is accumulated in.

Implementations

impl IntError

pub const fn message(self) -> &'static str

What to print, in GCC’s words where GCC has any.

The offending character is not in the message, because the caller has the spelling and the span and can say invalid suffix "ux" on integer constant the way GCC does.
