Enum Length 

pub enum Length {
    Cells(u16),
    Fill(NonZeroU16),
}

A box dimension: an absolute size, or a share of the remaining area.

Every length measures the box the terminal shows — content plus padding plus enabled border edges — with margin outside it. u16 converts into Length::Cells, so width(20) stays concise.

Variants

Cells(u16)

An absolute number of terminal cells.

Fill(NonZeroU16)

A weighted share of the area remaining to the box’s siblings.

Implementations

impl Length

pub const fn fill(weight: u16) -> Self

Creates a weighted share of the area remaining to the box’s siblings.

Use Length::try_fill when weight comes from input that may be zero.

Panics

Panics if weight is zero.

pub const fn try_fill(weight: u16) -> Result<Self, InvalidFillWeight>

Tries to create a weighted share of the remaining area.

Trait Implementations

impl Clone for Length

fn clone(&self) -> Length

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Length

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

Formats the value using the given formatter.

impl From<u16> for Length

fn from(value: u16) -> Self

Converts to this type from the input type.

impl PartialEq for Length

fn eq(&self, other: &Length) -> 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.

impl Copy for Length

impl Eq for Length

impl StructuralPartialEq for Length
