Struct ByColumnName

pub struct ByColumnName<S>(/* private fields */);

The structure is an implementaion of Locator to search for a column by it’s name. A name is considerent be a value in a first row.

So even if in reality there’s no header, first row will be consideret the one.

Implementations

impl<S> ByColumnName<S>

pub fn new(text: S) -> Self

where S: AsRef<str>,

Constructs a new object of the structure.

Trait Implementations

impl<S: Clone> Clone for ByColumnName<S>

fn clone(&self) -> ByColumnName<S>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<S: Debug> Debug for ByColumnName<S>

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

Formats the value using the given formatter.

impl<S> Locator for ByColumnName<S>

where S: AsRef<str>,

type Coordinate = usize

A coordinate of the finding.

type IntoIter = Vec<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<S> Object for ByColumnName<S>

where S: AsRef<str>,

type Iter = IntoIter<Entity>

An Iterator which returns a list of cells.

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

where R: 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.
