Struct NavigationStack 

pub struct NavigationStack { /* private fields */ }

The global navigation stack.

Bubba maintains a single, app-wide stack. You rarely interact with this directly — use the navigate() and navigate_back() free functions instead.

Implementations

impl NavigationStack

pub fn new() -> NavigationStack

Create an empty navigation stack.

pub fn push(&self, entry: ScreenEntry)

Push a new screen onto the stack.

pub fn pop(&self) -> bool

Pop the current screen (back navigation). Returns false if the stack has only one screen (can’t go further back).

pub fn current(&self) -> Option<Screen>

Build and return the current top-of-stack screen.

pub fn depth(&self) -> usize

How many screens are on the stack.

pub fn breadcrumbs(&self) -> Vec<&'static str>

Names of all screens on the stack, bottom → top.
