Struct NavigationStack 

pub struct NavigationStack { /* private fields */ }

A linear stack of HistoryEntry items with a movable cursor.

Implementations

impl NavigationStack

pub fn new() -> Self

pub fn push(&mut self, entry: HistoryEntry)

Push a new entry, discarding any forward history beyond the cursor.

pub fn replace_current(&mut self, entry: HistoryEntry)

Replace the current entry in-place (no forward-history truncation).

pub fn update_current( &mut self, title: Option<&str>, state: Option<Vec<u8>>, url: Option<&str>, )

Mutate selected fields of the current entry (used by guest push_state / replace_state when only updating metadata).

pub fn go_back(&mut self) -> Option<&HistoryEntry>

Move the cursor backward. Returns the new current entry.

pub fn go_forward(&mut self) -> Option<&HistoryEntry>

Move the cursor forward. Returns the new current entry.

pub fn can_go_back(&self) -> bool

pub fn can_go_forward(&self) -> bool

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

pub fn current_mut(&mut self) -> Option<&mut HistoryEntry>

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn current_index(&self) -> isize

pub fn entries(&self) -> &[HistoryEntry]
