Struct shortcut::cmp::Condition[−][src]

pub struct Condition<'a, T: Clone + 'a> {
    pub column: usize,
    pub cmp: Comparison<'a, T>,
}

A single condition to evaluate for a row in the dataset.

Fields

column: usize

The column of the row to use as the comparison value.

cmp: Comparison<'a, T>

The comparison to perform on the selected value.

Implementations

impl<'a, T: Ord + Clone + 'a> Condition<'a, T>[src]

pub fn matches<R: Row<T> + ?Sized>(&self, row: &R) -> bool[src]

Returns true if this condition holds true for the given row. To determine if this is the case, row[self.column] is extracted, and is evaluated using the comparison in self.cmp.
