Enum ColumnConstraint

pub enum ColumnConstraint {
    Hidden,
    ContentWidth,
    Absolute(Width),
    LowerBoundary(Width),
    UpperBoundary(Width),
    Boundaries {
        lower: Width,
        upper: Width,
    },
}

A Constraint can be added to a columns.

They allow some control over Column widths as well as the dynamic arrangement process.

All percental boundaries will be ignored, if:

• you aren’t using one of ContentArrangement::{Dynamic, DynamicFullWidth}
• the width of the table/terminal cannot be determined.

Variants

Hidden

This will completely hide a column.

ContentWidth

Force the column to be as long as it’s content. Use with caution! This can easily mess up your table formatting, if a column’s content is overly long.

Absolute(Width)

Enforce a absolute width for a column.

LowerBoundary(Width)

Specify a lower boundary, either fixed or as percentage of the total width. A column with this constraint will be at least as wide as specified. If the content isn’t as long as that boundary, it will be padded. If the column has longer content and is allowed to grow, the column may take more space.

UpperBoundary(Width)

Specify a upper boundary, either fixed or as percentage of the total width. A column with this constraint will be at most as wide as specified. The column may be smaller than that width.

Boundaries

Specify both, an upper and a lower boundary.

Fields

lower: Width

upper: Width

Trait Implementations

impl Clone for ColumnConstraint

fn clone(&self) -> ColumnConstraint

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ColumnConstraint

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

Formats the value using the given formatter.

impl PartialEq for ColumnConstraint

fn eq(&self, other: &ColumnConstraint) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
