Struct LibraryState 

pub struct LibraryState {
    pub tab: LibraryTab,
    pub selected: usize,
}

The page’s own state: which tab, and which row the cursor is on.

One cursor for both tabs, clamped to the active tab’s row count when the tab changes — so switching tabs never leaves the cursor past the end of a shorter list.

Fields

tab: LibraryTab

The active tab.

selected: usize

The selected row inside the active tab, 0-based.

Implementations

impl LibraryState

pub fn new() -> Self

A fresh page on the Views tab with the cursor on the first row.

pub fn move_selected(&mut self, delta: isize, rows: usize) -> bool

Move the cursor by delta rows, clamped to rows entries (which may be zero). Returns true when the cursor moved.

pub fn clamp_selected(&mut self, rows: usize)

Clamp the cursor into rows entries, for use after the registry changed underneath the page (a view deleted from another surface, say).
