Enum CDataModel

#[non_exhaustive]
pub enum CDataModel {

}

The C data model used on a target.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

LP32

The data model used most commonly on Win16. long and pointer are 32 bits.

ILP32

The data model used most commonly on Win32 and 32-bit Unix systems.

int, long, and pointer are all 32 bits.

LLP64

The data model used most commonly on Win64

long long, and pointer are 64 bits.

LP64

The data model used most commonly on 64-bit Unix systems

long, and pointer are 64 bits.

ILP64

A rare data model used on early 64-bit Unix systems

int, long, and pointer are all 64 bits.

Implementations

impl CDataModel

pub fn pointer_width(self) -> Size

The width of a pointer (in the default address space).

pub fn short_size(self) -> Size

The size of a C short. This is required to be at least 16 bits.

pub fn int_size(self) -> Size

The size of a C int. This is required to be at least 16 bits.

pub fn long_size(self) -> Size

The size of a C long. This is required to be at least 32 bits.

pub fn long_long_size(self) -> Size

The size of a C long long. This is required (in C99+) to be at least 64 bits.

pub fn float_size(self) -> Size

The size of a C float.

pub fn double_size(self) -> Size

The size of a C double.

Trait Implementations

impl Clone for CDataModel

fn clone(&self) -> CDataModel

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CDataModel

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for CDataModel

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for CDataModel

fn eq(&self, other: &CDataModel) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
