Struct Reader 

pub struct Reader { /* private fields */ }

Where a pane is in its value, and the units of text wrapped so far.

Implementations

impl Reader

pub fn prepare(&mut self, id: u64, width: usize, wrap: Wrap)

Read the pane id at width, wrapped as wrap.

pub fn carry(&mut self, old: &Content, new: &Content)

The same value built again at another width: a hex dump’s top row moves to the row holding the same offset.

pub fn take_formatted(&mut self) -> usize

Bytes wrapped since the last ask: what a key cost.

pub fn home(&mut self)

pub fn end(&mut self, c: &Content, h: usize)

The last rows of the value, filling a pane of h rows.

pub fn scroll(&mut self, c: &Content, h: usize, delta: isize)

Move delta rows, never past the top or past where the last row is at the bottom of a pane of h rows.

pub fn jump(&mut self, c: &Content, h: usize, pos: usize)

Put byte pos (a row, for lines) near the top of a pane of h rows.

pub fn window(&mut self, c: &Content, h: usize) -> Window

The rows of a pane of h rows from the top.

pub fn rows_needed(&mut self, c: &Content, cap: usize) -> usize

Rows the value takes, counted up to cap: how much of the pane it needs.

pub fn position_width(c: &Content) -> usize

The widest Self::position can be for c, so what sits beside it on the rule does not move as the pane scrolls.

pub fn position(&mut self, c: &Content, win: &Window) -> String

Where the pane is, for its rule: lines 41-73 of 4,000 · 1%, an offset range for bytes.

Trait Implementations

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Reader

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

Formats the value using the given formatter.

impl Default for Reader

fn default() -> Self

Returns the “default value” for a type.
