Fields

columns: Vec<String>

The view’s columns, in its order, as the screen opened: what ←→ step through.

at: usize

The column on screen, an index into columns.

order: Order

selected: usize

The line the cursor is on, and the first line drawn.

offset: usize

page: usize

Lines the last frame drew: what PgUp and PgDn move.

body_top: u16

Where the last frame’s listing (or histogram) began, under the summary.

computing: Option<Computing>

failed: Option<(String, String)>

Why the column on screen could not be counted.

drill_return: bool

Set by a drill from this screen: Esc out of that drill comes back here.

view: Option<CountsView>

The histogram or the listing, as chosen with c; None until then, which shows a number column’s histogram and anything else’s listing.

Implementations

impl ValueCountsModal

pub fn open(&mut self, columns: Vec<String>, at: usize, frame: u64)

Open on column at of columns, for the view frame. The counts held for another frame are of other rows, and go.

pub fn rebase(&mut self, frame: u64)

The view came back as it was (Esc out of a drill), under a new frame number.

pub fn column(&self) -> Option<&str>

pub fn current(&self) -> Option<&Arc<ValueCounts>>

The counts of the column on screen, once read.

pub fn hold(&mut self, counts: ValueCounts)

pub fn counting(&self) -> bool

Whether the column on screen is being counted.

pub fn step(&mut self, by: isize) -> bool

Step to the column by places over. Whether it moved.

pub fn shows_histogram(&self) -> bool

Whether the counts on screen show as a histogram: a number column’s do, until c turns to the listing.

pub fn toggle_view(&mut self)

c: between the histogram and the listing, where the column has both.

pub fn toggle_order(&mut self)

pub fn move_by(&mut self, by: isize)

Move the cursor by lines, staying on the listing.

pub fn move_to_end(&mut self)

pub fn move_to_start(&mut self)

pub fn selected_kind(&self) -> Option<LineKind>

What the line under the cursor stands for.

pub fn scroll_into_view(&mut self, height: usize)

Keep the cursor among the height lines drawn.

Trait Implementations

impl Debug for ValueCountsModal

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

Formats the value using the given formatter.

impl Default for ValueCountsModal

fn default() -> Self

Returns the “default value” for a type.
