Struct rquickjs_core::markers::Invariant

pub struct Invariant<'inv>(/* private fields */);

A marker struct which marks a lifetime as invariant.

Implementations

impl<'inv> Invariant<'inv>

pub fn new() -> Self

pub fn new_ref<T>(_v: &'inv T) -> Self

Trait Implementations

impl<'inv> Clone for Invariant<'inv>

fn clone(&self) -> Invariant<'inv>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'inv> Debug for Invariant<'inv>

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

Formats the value using the given formatter.

impl<'inv> Default for Invariant<'inv>

fn default() -> Invariant<'inv>

Returns the “default value” for a type.

impl<'inv> Hash for Invariant<'inv>

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<'inv> Ord for Invariant<'inv>

fn cmp(&self, other: &Invariant<'inv>) -> 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<'inv> PartialEq for Invariant<'inv>

fn eq(&self, other: &Invariant<'inv>) -> 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<'inv> PartialOrd for Invariant<'inv>

fn partial_cmp(&self, other: &Invariant<'inv>) -> 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.
