Trait Implementations

impl<T: Clone> Clone for UserRef<T>

fn clone(&self) -> UserRef<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for UserRef<T>

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

Formats the value using the given formatter.

impl<T: Default> Default for UserRef<T>

fn default() -> UserRef<T>

Returns the “default value” for a type.

impl<T> Deref for UserRef<T>

type Target = UserAddress

The resulting type after dereferencing.

fn deref(&self) -> &UserAddress

Dereferences the value.

impl<T> Display for UserRef<T>

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

Formats the value using the given formatter.

impl<T> From<UserAddress> for UserRef<T>

fn from(user_address: UserAddress) -> Self

Converts to this type from the input type.

impl<T> From<UserRef<T>> for UserAddress

fn from(user: UserRef<T>) -> UserAddress

Converts to this type from the input type.

impl<T> From<UserRef<T>> for uref<T>

fn from(value: UserRef<T>) -> Self

Converts to this type from the input type.

impl<T> From<uref<T>> for UserRef<T>

fn from(value: uref<T>) -> Self

Converts to this type from the input type.

impl<T: Hash> Hash for UserRef<T>

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<T: Ord> Ord for UserRef<T>

fn cmp(&self, other: &UserRef<T>) -> 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<T: PartialEq> PartialEq for UserRef<T>

fn eq(&self, other: &UserRef<T>) -> 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.

fn partial_cmp(&self, other: &UserRef<T>) -> 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.

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<T> TryFrom<UserBuffer> for UserRef<T>

fn try_from(buf: UserBuffer) -> Result<Self, Errno>

Returns EINVAL if the buffer is too small for the type.

type Error = Errno

The type returned in the event of a conversion error.
