Struct View 

pub struct View { /* private fields */ }

Available on crate feature inspect only.

Interaction state over a Timeline: scope, filter, selection and window.

Implementations

impl View

pub fn new(timeline: Timeline) -> View

Show timeline in full, with the first entry selected.

pub fn timeline(&self) -> &Timeline

The timeline being viewed.

pub fn filter(&self) -> &str

Active text filter.

pub fn set_filter(&mut self, filter: impl Into<String>)

Restrict to entries matching filter, keeping the selection when possible.

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

Connection scope, or None for all connections.

pub fn select_connection(&mut self, connection: Option<usize>)

Restrict to one connection, or to all when None.

pub fn cycle_connection(&mut self)

Cycle through “all connections” and each individual connection.

pub fn matches(&self) -> &[usize]

Indices, into Timeline::entries, of the entries currently shown.

pub fn visible(&self) -> impl ExactSizeIterator

Entries currently shown, in time order.

pub fn len(&self) -> usize

Number of entries currently shown.

pub fn is_empty(&self) -> bool

Whether the filter and scope hide every entry.

pub fn cursor(&self) -> usize

Position of the selection within View::visible.

pub fn selected(&self) -> Option<&Entry>

The selected entry, if any entry is shown.

pub fn select_next(&mut self)

Move the selection down, stopping at the last shown entry.

pub fn select_prev(&mut self)

Move the selection up, stopping at the first shown entry.

pub fn select_first(&mut self)

Select the first shown entry.

pub fn select_last(&mut self)

Select the last shown entry.

pub fn select(&mut self, position: usize)

Select by position within View::visible, clamped to what is shown.

pub fn window(&self) -> (Duration, Duration)

Visible time window as (start, end) offsets.

pub fn reset_window(&mut self)

Show the whole capture again.

pub fn zoom(&mut self, factor: f64)

Scale the window by factor around the selection (< 1 zooms in).

The window never shrinks below a millisecond and never grows past the capture’s own span.

pub fn pan(&mut self, fraction: f64)

Slide the window by fraction of its width, staying inside the capture.

pub fn bar(&self, entry: &Entry) -> Option<(f64, f64)>

Where entry sits in the window, as (start, end) fractions in 0..=1.

None when the entry falls entirely outside the window.

Trait Implementations

impl Clone for View

fn clone(&self) -> View

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for View

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

Formats the value using the given formatter.
