Struct CharConstant 

pub struct CharConstant {
    pub value: i64,
    pub encoding: Encoding,
    pub remarks: Remarks,
}

A converted character constant.

Fields

value: i64

The value, already converted to the constant’s type, which is why it can be negative: '\xff' is minus one where plain char is signed.

encoding: Encoding

The prefix it was written with.

remarks: Remarks

What is worth saying about it, for the caller that holds the span.

Implementations

impl CharConstant

pub fn spell(self) -> String

The spelling this constant would be written with, quotes and prefix included.

It is a spelling and not the spelling: the one the author wrote is gone by the time there is a value here. What it guarantees is that reading it back gives this constant, which is what a printer downstream needs and what a message quoting a constant wants.

A constant holding more than one character is written as the bytes it was shifted together from, most significant first, which is how it is read back.
