Implementations

impl TreeModel

pub fn from_json(data: &JsonValue, home: Option<String>) -> Self

Builds the model from get_tree data ({tree, leafId}).

pub fn new( roots: &[TreeNode], leaf_id: Option<String>, home: Option<String>, ) -> Self

Builds the model from parsed roots.

pub fn len(&self) -> usize

Number of visible rows.

pub fn is_empty(&self) -> bool

No visible rows.

pub const fn selected(&self) -> usize

Selected visible index.

pub fn selected_entry(&self) -> Option<&SessionEntry>

Selected entry.

pub fn selected_label(&self) -> Option<&str>

Label of the selected entry.

pub fn move_by(&mut self, delta: isize)

Moves the selection (wrapping, tui.select.up/down).

pub fn page(&mut self, delta: isize)

Pages the selection (clamped).

pub fn fold_or_up(&mut self)

A p p . t r e e . f o l d O r U p.

pub fn unfold_or_down(&mut self)

A p p . t r e e . u n f o l d O r D o w n.

pub fn set_filter(&mut self, mode: FilterMode)

Sets the filter mode (clears folds).

pub fn toggle_filter(&mut self, mode: FilterMode)

Toggle semantics: mode ↔ default.

pub fn cycle_filter(&mut self, forward: bool)

Cycles the filter.

pub fn set_query(&mut self, query: impl Into<String>)

pub fn set_label( &mut self, entry_id: &str, label: Option<String>, timestamp: Option<String>, )

Updates a label after _oino/set_label.

pub fn status(&self) -> String

Status line: (n/total) plus filter labels.

pub fn rows(&self, start: usize, end: usize) -> Vec<TreeRow>

Rows start..end of the visible list.

pub fn window(&self, height: usize) -> (usize, usize)

Windowing: centre the selection in height rows.

pub fn selected_copy_text(&self) -> Option<String>

getEntryCopyText for the selected entry.
