Struct Instances 

pub struct Instances<M: SurfaceModel> { /* private fields */ }

The instances of a pane.footer or pane.header surface (one per pane the viewer shows, named <surface>@<pane>) or of a machine.after surface (one per machine, <surface>@<machine>). Pass every event to Instances::event; it creates an instance’s surface when the viewer first sizes it and drops it when the viewer removes it (a zero-size resize), and says which pane or machine changed.

Implementations

impl<M: SurfaceModel> Instances<M>

pub fn new(surface: &str) -> Self

The instances of the manifest’s surface surface.

pub fn event(&mut self, event: &Event) -> Option<String>

Follows the viewer: returns the pane whose instance the event is about (created, resized, shown, hidden or removed), if any.

pub fn get_mut(&mut self, pane: &str) -> Option<&mut Surface<M>>

pub fn instance(&mut self, owner: &str) -> &mut Surface<M>

The instance of owner (a pane, machine or project id), created when the viewer has not shown it yet: a machine or project row at zero rows asks for rows through it (Surface::request_size).

pub fn iter_mut(&mut self) -> impl Iterator<Item = (&str, &mut Surface<M>)>

Every live instance, by pane.

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

Trait Implementations

impl<M: Debug + SurfaceModel> Debug for Instances<M>

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

Formats the value using the given formatter.
