Enum FloatSize 

pub enum FloatSize {
    Float,
    Double,
    LongDouble,
    Float32,
    Float64,
    Float32x,
    Float64x,
    Float128,
}

Rank of a standard floating type.

Variants

Float

float

Double

double

LongDouble

long double

Float32

TS 18661-3’s _Float32, which is float.

Float64

_Float64, which is double.

Float32x

_Float32x, which is double.

Float64x

_Float64x, which is whatever long double is.

Float128

_Float128 (and GCC’s __float128): binary128, which has no Rust type. It may be named — in a prototype, a typedef, a pointer — but sema refuses every value of it.

Implementations

impl FloatSize

pub fn as_str(self) -> &'static str

The type as C spells it.

pub fn is_floatn(self) -> bool

Whether this is one of the _FloatN spellings, which GCC makes types distinct from float, double and long double even where they have the same format; see _Generic in sema.
