Struct Constant

pub struct Constant {
    pub value: u64,
    pub bits: usize,
}

A constant value.

Fields

value: u64

Value

bits: usize

Size of the value in bits. Never zero.

Implementations

impl Constant

pub fn new(value: u64, bits: usize) -> Result<Constant>

Create a new constant. Fails if bits is zero.

pub fn mask(&self) -> Wrapping<u64>

Returns a bit mask covering all bits of the constant. Returns u64::MAX if bits > 64.

Trait Implementations

impl Arbitrary for Constant

fn arbitrary<G: Gen>(g: &mut G) -> Self

fn shrink(&self) -> Box<dyn Iterator<Item = Self>>

impl Clone for Constant

fn clone(&self) -> Constant

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Constant

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

Formats the value using the given formatter.

impl From<Constant> for Value

fn from(v: Constant) -> Value

Converts to this type from the input type.

impl Hash for Constant

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 Into<Wrapping<u64>> for Constant

fn into(self) -> Wrapping<u64>

Converts this type into the (usually inferred) input type.

impl Ord for Constant

fn cmp(&self, other: &Constant) -> 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 PartialEq for Constant

fn eq(&self, other: &Constant) -> 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 PartialOrd for Constant

fn partial_cmp(&self, other: &Constant) -> 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.
