Enum DockLayout 

#[non_exhaustive]
pub enum DockLayout {
    Split {
        axis: DockAxis,
        ratio: f32,
        first: Box<DockLayout>,
        second: Box<DockLayout>,
    },
    Tabs {
        panels: Vec<String>,
        shown: usize,
    },
}

How a dock’s panels are arranged, naming panels by their keys (DockPanel::with_key): what DockArea::layout saves and DockArea::restore_layout puts back, for example when an application starts again.

It is written as text (to_string()) and read back with str::parse: densa-dock 1 (row 0.6 (tabs 0 "orders" "trades") (tabs 0 "chart")), a version then the tree, each split with its axis and the fraction its first part takes, each group with the position of its shown tab and its panels’ keys (quoted, \" and \\ escaped). Layouts built in code are written however deep they are, but only those within MAX_LAYOUT_DEPTH read back.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Split

Two parts sharing a rectangle along axis; ratio (0 to 1) of it is the first’s.

Fields

axis: DockAxis

Which way the parts sit.

ratio: f32

The fraction of the rectangle the first part takes.

first: Box<DockLayout>

The left or upper part.

second: Box<DockLayout>

The right or lower part.

Tabs

A group of tabs: its panels’ keys in tab order, and the position of the shown one.

Fields

panels: Vec<String>

The panels’ keys, in tab order.

shown: usize

Which of them is shown.

Trait Implementations

impl Clone for DockLayout

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DockLayout

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

Formats the value using the given formatter.

impl Display for DockLayout

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

Formats the value using the given formatter.

impl FromStr for DockLayout

fn from_str(text: &str) -> Result<Self, Self::Err>

Reads a layout written by to_string().

Errors

DockLayoutError for another format or version, a ratio that is not a number from 0 to 1, a group without panels or showing a tab it lacks, splits nested deeper than MAX_LAYOUT_DEPTH, or anything after the layout; see DockLayoutErrorKind.

type Err = DockLayoutError

The associated error which can be returned from parsing.

impl PartialEq for DockLayout

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

Equality operator ==.

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

Inequality operator !=.
