Struct wnf::StampedData

pub struct StampedData<T> { /* private fields */ }

State data together with a change stamp

Implementations

impl<T> StampedData<T>

pub fn from_data_change_stamp( data: T, change_stamp: impl Into<ChangeStamp> ) -> Self

Creates a new StampedData from the given data and change stamp

pub fn into_data_change_stamp(self) -> (T, ChangeStamp)

Moves the contained data and change stamp out of this StampedData

pub fn into_data(self) -> T

Moves the contained data out of this StampedData, discarding the change stamp

pub const fn data(&self) -> &T

Returns a reference to the data contained in this StampedData

pub const fn change_stamp(&self) -> ChangeStamp

Returns the change stamp contained in this StampedData

pub fn map<U, F>(self, op: F) -> StampedData<U>

where F: FnOnce(T) -> U,

Returns a new StampedData obtained by applying a given closure to the contained data

Trait Implementations

impl<T> AsMut<T> for StampedData<T>

fn as_mut(&mut self) -> &mut T

Converts this type into a mutable reference of the (usually inferred) input type.

impl<T> AsRef<T> for StampedData<T>

fn as_ref(&self) -> &T

Converts this type into a shared reference of the (usually inferred) input type.

impl<T: Clone> Clone for StampedData<T>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for StampedData<T>

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

Formats the value using the given formatter.

impl<T: Default> Default for StampedData<T>

fn default() -> StampedData<T>

Returns the “default value” for a type.

impl<T> From<(T, ChangeStamp)> for StampedData<T>

fn from((data, change_stamp): (T, ChangeStamp)) -> Self

Converts to this type from the input type.

impl<T> From<StampedData<T>> for (T, ChangeStamp)

fn from(stamped_data: StampedData<T>) -> Self

Converts to this type from the input type.

impl<T: Hash> Hash for StampedData<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: PartialEq> PartialEq for StampedData<T>

fn eq(&self, other: &StampedData<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.
