Struct TreePresentation 

pub struct TreePresentation { /* private fields */ }

Presentation policy used to compose a Tree into a View.

Implementations

impl TreePresentation

pub fn new( root_style: TextStyle, item_style: TextStyle, connector_style: TextStyle, ) -> Self

Creates the canonical tree presentation with square line glyphs.

pub fn get_style(&self, role: TreeRole) -> &TextStyle

Returns the style assigned to one logical tree role.

pub fn style(self, role: TreeRole, style: TextStyle) -> Self

Replaces the style assigned to one logical tree role.

pub fn root_style(self, style: TextStyle) -> Self

Replaces the root style.

pub fn item_style(self, style: TextStyle) -> Self

Replaces the item style.

pub fn connector_style(self, style: TextStyle) -> Self

Replaces the connector style.

pub const fn line_glyphs(self, line_glyphs: LineGlyphs) -> Self

Replaces the complete one-cell connector glyph repertoire.

pub const fn indent_width(self, indent_width: usize) -> Self

Sets the cell distance from one connector column to the next.

The width includes the junction, at least one horizontal continuation cell, and one gap before the node body.

Panics

Panics when indent_width is less than three cells.

pub fn compose<T>(&self, tree: &Tree<T>) -> View

where T: Display,

Composes displayable tree data into an intrinsically sized Canvas.

pub fn compose_with<T>( &self, tree: &Tree<T>, nodes: &TreeNodePresentation<'_, T>, ) -> View

Composes tree data with typed node formatting and text-style overrides.

Trait Implementations

impl Clone for TreePresentation

fn clone(&self) -> TreePresentation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TreePresentation

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

Formats the value using the given formatter.

impl PartialEq for TreePresentation

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