Trait FilterRow

pub trait FilterRow {
    // Required method
    fn filter_row(
        &self,
        typ: LineType,
        irow: usize,
        row: &[(Cow<'_, str>, [usize; 2])],
    ) -> bool;

    // Provided method
    fn need_args(&self) -> bool { ... }
}

Filter columns of a table to print it only partially.

Required Methods

fn filter_row( &self, typ: LineType, irow: usize, row: &[(Cow<'_, str>, [usize; 2])], ) -> bool

Filter rows of a table to print it only partially.

Provided Methods

fn need_args(&self) -> bool

Determine is arguments needed for the filter or it can give answer even without arguments. Useful for optimization.
