Trait Implementations

impl<'a, T: Type, C: Color> AsMut<[T]> for DataMut<'a, T, C>

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

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

impl<'a, T: Type, C: Color> AsRef<[T]> for DataMut<'a, T, C>

fn as_ref(&self) -> &[T]

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

impl<'a, T: Debug + 'a + Type, C: Debug + 'a + Color> Debug for DataMut<'a, T, C>

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

Formats the value using the given formatter.

impl<'a, T: Type, C: Color> Index<usize> for DataMut<'a, T, C>

type Output = T

The returned type after indexing.

fn index(&self, i: usize) -> &T

Performs the indexing (container[index]) operation.

impl<'a, T: Type, C: Color> IndexMut<usize> for DataMut<'a, T, C>

fn index_mut(&mut self, i: usize) -> &mut T

Performs the mutable indexing (container[index]) operation.

impl<'a, T: 'a + Type, C: 'a + Color> IntoIterator for DataMut<'a, T, C>

type Item = &'a mut T

The type of the elements being iterated over.

type IntoIter = IterMut<'a, T>

Which kind of iterator are we turning this into?

fn into_iter(self) -> IterMut<'a, T>

Creates an iterator from a value.

impl<'a, T: PartialEq + 'a + Type, C: PartialEq + 'a + Color> PartialEq<DataMut<'a, T, C>> for DataMut<'a, T, C>

fn eq(&self, other: &DataMut<'a, T, C>) -> 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<'a, T: PartialOrd + 'a + Type, C: PartialOrd + 'a + Color> PartialOrd<DataMut<'a, T, C>> for DataMut<'a, T, C>

fn partial_cmp(&self, other: &DataMut<'a, T, C>) -> 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.
