Implementations

impl<Tab> Node<Tab>

pub fn leaf(tab: Tab) -> Self

Constructs a leaf node with a given tab.

pub const fn leaf_with(tabs: Vec<Tab>) -> Self

Constructs a leaf node with a given list of tabs.

pub fn set_rect(&mut self, new_rect: Rect)

Sets the area occupied by the node.

pub const fn is_empty(&self) -> bool

Returns true if the node is a Empty, false otherwise.

pub const fn is_leaf(&self) -> bool

Returns true if the node is a Leaf, false otherwise.

pub const fn is_horizontal(&self) -> bool

Returns true if the node is a Horizontal, false otherwise.

pub const fn is_vertical(&self) -> bool

Returns true if the node is a Vertical, false otherwise.

pub const fn is_parent(&self) -> bool

Returns true if the node is either Horizontal or Vertical, false otherwise.

pub fn split(&mut self, split: Split, fraction: f32) -> Self

Replaces the node with a Horizontal or Vertical one (depending on split) and assigns it an empty rect.

pub fn append_tab(&mut self, tab: Tab)

Adds a tab to the node.

Panics

Panics if the new capacity of tabs exceeds isize::MAX bytes.

pub fn insert_tab(&mut self, index: TabIndex, tab: Tab)

Adds a tab to the node.

Panics

Panics if the new capacity of tabs exceeds isize::MAX bytes. index > tabs_count()

pub fn remove_tab(&mut self, tab_index: TabIndex) -> Option<Tab>

Removes a tab at given index from the node. Returns the removed tab if the node is a Leaf, or None otherwise.

Panics

Panics if index is out of bounds.

pub fn tabs_count(&self) -> usize
