Struct gridly::grid::SingleView

pub struct SingleView<'a, G: Grid + ?Sized, T: LocComponent> { /* private fields */ }

View of a single Row or Column of a grid.

A SingleView provides a view over a single row or column of a grid, based on its generic parameter. For instance, a SingleView<’a, G, Row> is a view over a single row of a grid.

A SingleView can be indexed; for instance, a RowView can be indexed with a Column to a get a specific cell.

Implementations

impl<'a, G: Grid + ?Sized, T: LocComponent> SingleView<'a, G, T>

pub fn len(&self) -> <T::Converse as LocComponent>::Distance

Get the length of this view. For example, for a SingleView<'a, G, Row>, get the number of columns.

pub fn index(&self) -> T

Get the index of the Row or Column that this view represents. This index is safely guaranteed to have been bounds checked when the SingleView was constructed.

pub unsafe fn get_unchecked(&self, cross: T::Converse) -> &'a G::Item

Get a particular cell in the row or column by an index, without bounds checking the index.

Safety

Callers must ensure that the index has been bounds-checked before calling this method.

pub fn get( &self, cross: T::Converse ) -> Result<&'a G::Item, RangeError<T::Converse>>

Get a particular cell in the row or column, or return an error if the index is out of bounds.

pub fn range(&self) -> LocationRange<T>

Get the specific locations associated with this view.

pub fn iter( &self ) -> impl Iterator<Item = &'a G::Item> + DoubleEndedIterator + FusedIterator + ExactSizeIterator + Debug + Clone

Get an iterator over the cells in this row or column

pub fn iter_with_locations( &self ) -> impl Iterator<Item = (Location, &'a G::Item)> + DoubleEndedIterator + FusedIterator + ExactSizeIterator + Debug + Clone

Get an iterator over (Location, &Item) pairs for this row or column.

pub fn iter_with_indices( &self ) -> impl Iterator<Item = (T::Converse, &'a G::Item)> + DoubleEndedIterator + FusedIterator + ExactSizeIterator + Debug + Clone

Get an iterator over (Index, &Item) pairs for this column. For instance, for a RowView, this iterates over (Column, &Item) pairs.

impl<'a, G: Grid + ?Sized> SingleView<'a, G, Row>

pub fn column( &self, column: impl Into<Column> ) -> Result<&'a G::Item, ColumnRangeError>

Get a reference to the cell in a specific column of this view’s row.

impl<'a, G: Grid + ?Sized> SingleView<'a, G, Column>

pub fn row(&self, row: impl Into<Row>) -> Result<&'a G::Item, RowRangeError>

Get a reference to the cell in a specific row of this view’s column.

Trait Implementations

impl<'a, G: Grid + ?Sized, T: LocComponent> Clone for SingleView<'a, G, T>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a, G: Debug + Grid + ?Sized, T: Debug + LocComponent> Debug for SingleView<'a, G, T>

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

Formats the value using the given formatter.

impl<'a, G: Grid + ?Sized, T: LocComponent> Index<<T as Component>::Converse> for SingleView<'a, G, T>

type Output = <G as Grid>::Item

The returned type after indexing.

fn index(&self, idx: T::Converse) -> &G::Item

Performs the indexing (container[index]) operation.
