Browser-like back/forward history.

Implementations

impl HistoryStack

pub fn new() -> Self

Creates an empty history stack.

pub fn visit(&mut self, url: IndexUrl)

Visits a URL and clears the forward stack.

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

Visits a fully described history entry and clears the forward stack.

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

Moves one step back and returns the new current entry.

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

Moves one step forward and returns the new current entry.

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

Returns the current history entry.

pub fn can_go_back(&self) -> bool

Returns whether back navigation is available.

pub fn can_go_forward(&self) -> bool

Returns whether forward navigation is available.

pub fn entries(&self) -> Vec<&HistoryEntry>

Returns all entries in display order.

pub fn current_index(&self) -> Option<usize>

Returns the current entry index in entries.

Trait Implementations

impl Clone for HistoryStack

fn clone(&self) -> HistoryStack

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HistoryStack

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for HistoryStack

fn default() -> HistoryStack

Returns the “default value” for a type.

impl PartialEq for HistoryStack

fn eq(&self, other: &HistoryStack) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
