Struct flatcontainer::impls::slice::ReadSlice

pub struct ReadSlice<'a, R: Region, O: OffsetContainer<R::Index> = Vec<<R as Region>::Index>>(/* private fields */);

A helper to read data out of a slice region.

Implementations

impl<R: Region, O: OffsetContainer<R::Index>> ReadSlice<'_, R, O>

pub fn get(&self, index: usize) -> R::ReadItem<'_>

Read the n-th item from the underlying region.

Panics

Panics if the index is out of bounds, i.e., it is larger than the length of this slice representation.

pub fn len(&self) -> usize

The number of elements in this slice.

pub fn is_empty(&self) -> bool

Returns true if the slice is empty.

pub fn iter(&self) -> <Self as IntoIterator>::IntoIter

Returns an iterator over all contained items.

Trait Implementations

impl<R: Region, O: OffsetContainer<R::Index>> Clone for ReadSlice<'_, R, O>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<R: Region, O: OffsetContainer<R::Index>> Debug for ReadSlice<'_, R, O>

where for<'a> R::ReadItem<'a>: Debug,

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

Formats the value using the given formatter.

impl<'a, R: Region, O: OffsetContainer<R::Index>> IntoIterator for ReadSlice<'a, R, O>

type Item = <R as Region>::ReadItem<'a>

The type of the elements being iterated over.

type IntoIter = ReadSliceIter<'a, R, O>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl<'a, R, O> IntoOwned<'a> for ReadSlice<'a, R, O>

where R: Region, O: OffsetContainer<R::Index>,

type Owned = Vec<<R as Region>::Owned>

Owned type into which this type can be converted.

fn into_owned(self) -> Self::Owned

Conversion from an instance of this type to the owned type.

fn clone_onto(self, other: &mut Self::Owned)

Clones self onto an existing instance of the owned type.

fn borrow_as(owned: &'a Self::Owned) -> Self

Borrows an owned instance as oneself.

impl<R: Region, O: OffsetContainer<R::Index>> Ord for ReadSlice<'_, R, O>

where for<'a> R::ReadItem<'a>: Ord,

fn cmp(&self, other: &Self) -> 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<R: Region, O: OffsetContainer<R::Index>> PartialEq for ReadSlice<'_, R, O>

where for<'a> R::ReadItem<'a>: PartialEq,

fn eq(&self, other: &Self) -> 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<R: Region, O: OffsetContainer<R::Index>> PartialOrd for ReadSlice<'_, R, O>

where for<'a> R::ReadItem<'a>: PartialOrd,

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

impl<'a, C, O> Push<ReadSlice<'a, C, O>> for SliceRegion<C, O>

where C: Region + Push<<C as Region>::ReadItem<'a>>, O: OffsetContainer<C::Index>,

fn push( &mut self, item: ReadSlice<'a, C, O>, ) -> <SliceRegion<C, O> as Region>::Index

Push item into self, returning an index that allows to look up the corresponding read item.

impl<'a, R, O> ReserveItems<ReadSlice<'a, R, O>> for SliceRegion<R, O>

where R: Region + ReserveItems<<R as Region>::ReadItem<'a>> + 'a, O: OffsetContainer<R::Index>,

fn reserve_items<I>(&mut self, items: I)

where I: Iterator<Item = ReadSlice<'a, R, O>> + Clone,

Ensure that the region can absorb items without reallocation.
