Struct History 

pub struct History {
    pub content: Vec<PathBuf>,
    pub index: usize,
}

A stack of visited paths. We save the last folder and the selected file every time a PatchContent is updated. We also ensure not to save the same pair multiple times.

Fields

content: Vec<PathBuf>

index: usize

Implementations

impl History

pub fn push(&mut self, file: &Path)

Add a new path and a selected file in the stack, without duplicates, and select the last one.

pub fn drop_queue(&mut self)

Drop the last visited paths from the stack, after the selected one. Used to go back a few steps in time.

pub fn is_this_the_last(&self, path: &Path) -> bool

True iff the last element of the stack has the same path as the one given. Doesn’t check the associated file. false if the stack is empty.

Trait Implementations

impl Clone for History

fn clone(&self) -> History

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Content<PathBuf> for History

Implement a selectable content for this struct. This trait allows to navigate through a vector of element content_type. It implements: is_empty, len, next, prev, selected. selected returns an optional reference to the value.

fn selected(&self) -> Option<&PathBuf>

Returns a reference to the selected content.

fn content(&self) -> &Vec<PathBuf>

A reference to the content.

fn style(&self, index: usize, style: &Style) -> Style

Reverse the received effect if the index match the selected index.

fn push(&mut self, element: PathBuf)

Push a new element at the end of content

impl Default for History

fn default() -> History

Returns the “default value” for a type.

impl DrawMenu<PathBuf> for History

fn draw_menu(&self, f: &mut Frame<'_>, rect: &Rect, window: &ContentWindow)

where Self: Content<T>,

impl Selectable for History

Implement a selectable content for this struct. This trait allows to navigate through a vector of element content_type. It implements: is_empty, len, next, prev, selected. selected returns an optional reference to the value.

fn is_empty(&self) -> bool

True if the content is empty.

fn len(&self) -> usize

The size of the content.

fn prev(&mut self)

Select the prev item.

fn next(&mut self)

Select the next item.

fn index(&self) -> usize

Returns the index of the selected item.

fn set_index(&mut self, index: usize)

Set the index to a new value if the value is below the length.

fn selected_is_last(&self) -> bool

true if the selected element is the last of content
