Struct NavigationHistoryState 

pub struct NavigationHistoryState {
    Stack: Arc<Mutex<Vec<String>>>,
    Index: Arc<Mutex<usize>>,
}

Tracks the editor navigation history stack (back/forward).

Implements a cursor-based navigation stack where Index points to the current position. GoBack decrements the index; GoForward increments it. Pushing a new entry truncates forward history.

Fields

Stack: Arc<Mutex<Vec<String>>>

The ordered list of visited URIs (oldest first).

Index: Arc<Mutex<usize>>

Current position in the stack (0-based). Points to the active entry.

Implementations

impl NavigationHistoryState

pub fn CanGoBack(&self) -> bool

Returns true if there is a previous location to navigate to.

pub fn CanGoForward(&self) -> bool

Returns true if there is a next location to navigate to.

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

Decrement the history index (go back). Returns the URI now active, or None if already at the beginning.

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

Increment the history index (go forward). Returns the URI now active, or None if already at the end.

pub fn Push(&self, Uri: String)

Push a URI onto the navigation stack. Truncates any forward history beyond the current index.

pub fn Clear(&self)

Clear the entire navigation stack.

pub fn GetStack(&self) -> Vec<String>

Return all URIs in the stack (oldest first).

Trait Implementations

impl Clone for NavigationHistoryState

fn clone(&self) -> NavigationHistoryState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for NavigationHistoryState

fn default() -> Self

Returns the “default value” for a type.
