Enum PointerWidth

#[non_exhaustive]
pub enum PointerWidth<'a> {
    U16,
    U32,
    U64,
    Other(Cow<'a, str>),
}

The endianness of the target architecture.

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.

U16

16-bit pointer width. 16

U32

32-bit pointer width. 32

U64

64-bit pointer width. 64

Other(Cow<'a, str>)

Unknown value

Implementations

impl<'a> PointerWidth<'a>

pub fn as_str(&self) -> &str

String representing this target pointer width which matches #[cfg(target_pointer_width)]

pub fn from_str(name: impl Into<Cow<'a, str>>) -> Self

Tries to parse the given string as a PointerWidth falling back to PointerWidth::Other for unknown values.

impl PointerWidth<'_>

pub fn target() -> Result<Self, VarError>

Gets the current target PointerWidth.

Trait Implementations

impl<'a> Clone for PointerWidth<'a>

fn clone(&self) -> PointerWidth<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for PointerWidth<'a>

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

Formats the value using the given formatter.

impl Display for PointerWidth<'_>

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

Formats the value using the given formatter.

impl From<u8> for PointerWidth<'_>

fn from(value: u8) -> Self

Converts to this type from the input type.

impl<'a> Hash for PointerWidth<'a>

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<'a> Ord for PointerWidth<'a>

fn cmp(&self, other: &PointerWidth<'a>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<'a> PartialEq for PointerWidth<'a>

fn eq(&self, other: &PointerWidth<'a>) -> 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.

impl<'a> PartialOrd for PointerWidth<'a>

fn partial_cmp(&self, other: &PointerWidth<'a>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl TryFrom<PointerWidth<'_>> for u8

type Error = ParseIntError

The type returned in the event of a conversion error.

fn try_from(value: PointerWidth<'_>) -> Result<Self, Self::Error>

Performs the conversion.
