Struct TreeNodePresentation 

pub struct TreeNodePresentation<'a, T> { /* private fields */ }

Typed formatting and optional text-style overrides for Tree values.

This policy covers both the optional root and child nodes. It is separate from TreePresentation, which remains the type-independent Tree-wide presentation stored by a Theme. Composition snapshots callback results; measurement and drawing do not evaluate application policy.

Implementations

impl<'a, T: 'a> TreeNodePresentation<'a, T>

pub fn new<F>(format: F) -> Self

where F: Fn(&T, TreePosition) -> String + 'a,

Creates a node presentation with a custom formatter and no style overrides.

pub fn node_style<S>(self, node_style: S) -> Self

where S: Fn(&T, TreePosition) -> Option<TextStyle> + 'a,

Replaces the per-node text-style policy.

None keeps the TreePresentation root or item default. Some(style) replaces that complete style rather than layering over it.

impl<'a, T> TreeNodePresentation<'a, T>

where T: Display + 'a,

pub fn display() -> Self

Uses the value’s canonical fmt::Display representation.

Trait Implementations

impl<'a, T: Clone> Clone for TreeNodePresentation<'a, T>

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

Performs copy-assignment from source.

impl<T> Debug for TreeNodePresentation<'_, T>

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