Struct Available 

pub struct Available { /* private fields */ }

The area a view may occupy: an input to layout, not an afterthought.

A terminal width or a Ratatui Rect becomes an Available. It flows down the tree and each node resolves its own size under it, so a frame closes at whatever size the area forces. It is not a clip applied to a finished rectangle; the only crop left is the degenerate-case safety net in resolve.

An absent bound is not zero: it means the axis is unbounded, which is what measure resolves under and what makes an intrinsic size the same computation as a bounded one.

Implementations

impl Available

pub const NONE: Self

Imposes no bound on either axis.

pub const fn new(width: Option<usize>, height: Option<usize>) -> Self

pub const fn columns(width: usize) -> Self

Bounds the width only — a terminal of a known width and no known height.

pub const fn size(width: usize, height: usize) -> Self

Bounds both axes.

pub const fn width(&self) -> Option<usize>

pub const fn height(&self) -> Option<usize>

Trait Implementations

impl Clone for Available

fn clone(&self) -> Available

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Available

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

Formats the value using the given formatter.

impl Default for Available

fn default() -> Available

Returns the “default value” for a type.

impl PartialEq for Available

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