Struct Rows

pub struct Rows<R> { /* private fields */ }

Row denotes a set of cells on given rows on a Table.

Implementations

impl<R> Rows<R>

pub fn new(range: R) -> Self

where R: RangeBounds<usize>,

Returns a new instance of Rows for a range of rows.

If the boundaries are exceeded it may panic.

impl Rows<()>

pub fn single(index: usize) -> Row

Returns a new instance of Rows with a single row.

If the boundaries are exceeded it may panic.

pub fn first() -> FirstRow

Returns a first row Object.

If the table has 0 rows returns an empty set of cells.

pub fn last() -> LastRow

Returns a last row Object.

If the table has 0 rows returns an empty set of cells.

Trait Implementations

impl<R: Debug> Debug for Rows<R>

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

Formats the value using the given formatter.

impl<B> Locator for Rows<B>

where B: RangeBounds<usize>,

type Coordinate = usize

A coordinate of the finding.

type IntoIter = Range<usize>

An iterator of the coordinates. If it’s empty it’s consideret that nothing is found.

fn locate<R>(&mut self, records: R) -> Self::IntoIter

where R: Records,

Search for the thing in Records, returning a list of coordinates.

impl<R> Object for Rows<R>

where R: RangeBounds<usize>,

type Iter = RowsIter

An Iterator which returns a list of cells.

fn cells<T>(&self, table: &Table<T>) -> Self::Iter

where T: Records,

Cells returns a set of coordinates of cells

fn and<O>(self, rhs: O) -> UnionCombination<Self, O>

where O: Object,

Combines cells. It doesn’t repeat cells.

fn not<O>(self, rhs: O) -> DiffCombination<Self, O>

where O: Object,

Excludes rhs cells from this cells.

fn intersect<O>(self, rhs: O) -> IntersectionCombination<Self, O>

where O: Object,

Returns cells which are present in both Objects only.

fn inverse(self) -> InversionCombination<Self>

Returns cells which are not present in target Object.
