Implementations

impl Integer

pub fn size(self) -> Size

pub fn from_attr<C: HasDataLayout>(cx: &C, ity: IntegerType) -> Integer

Gets the Integer type from an IntegerType.

pub fn align<C: HasDataLayout>(self, cx: &C) -> AbiAndPrefAlign

pub fn signed_max(self) -> i128

Returns the largest signed value that can be represented by this Integer.

pub fn fit_signed(x: i128) -> Integer

Finds the smallest Integer type which can represent the signed value.

pub fn fit_unsigned(x: u128) -> Integer

Finds the smallest Integer type which can represent the unsigned value.

pub fn for_align<C: HasDataLayout>(cx: &C, wanted: Align) -> Option<Integer>

Finds the smallest integer with the given alignment.

pub fn approximate_align<C: HasDataLayout>(cx: &C, wanted: Align) -> Integer

Find the largest integer with the given alignment or less.

pub fn from_size(size: Size) -> Result<Self, String>

Trait Implementations

impl Clone for Integer

fn clone(&self) -> Integer

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Integer

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

Formats the value using the given formatter.

impl<__D: Decoder> Decodable<__D> for Integer

fn decode(__decoder: &mut __D) -> Self

impl<__E: Encoder> Encodable<__E> for Integer

fn encode(&self, __encoder: &mut __E)

impl Hash for Integer

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<__CTX> HashStable<__CTX> for Integer

where __CTX: HashStableContext,

fn hash_stable(&self, __hcx: &mut __CTX, __hasher: &mut StableHasher)

impl Ord for Integer

fn cmp(&self, other: &Integer) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for Integer

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for Integer

fn partial_cmp(&self, other: &Integer) -> Option<Ordering>

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl Copy for Integer

impl Eq for Integer

impl StructuralPartialEq for Integer

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
