Struct LineNumbers 

pub struct LineNumbers<'a> { /* private fields */ }

Renders line-numbers.

Stateful

This widget implements StatefulWidget, you can use it with LineNumberState to handle common actions.

Implementations

impl<'a> LineNumbers<'a>

pub fn new() -> LineNumbers<'a>

pub fn with_textarea(self, text_area: &'a TextAreaState) -> LineNumbers<'a>

Sync with this text-area.

To make this work correctly, the TextArea must be rendered first to make sure that all layout-information stored in the state is accurate.

pub fn start(self, start: u32) -> LineNumbers<'a>

Start position.

pub fn end(self, end: u32) -> LineNumbers<'a>

End position.

pub fn cursor(self, cursor: u32) -> LineNumbers<'a>

Current line for highlighting.

pub fn relative(self, relative: bool) -> LineNumbers<'a>

Numbering relative to cursor

pub fn flags(self, flags: Vec<Line<'a>>) -> LineNumbers<'a>

Extra info.

This is a Vec that matches up the visible lines.

pub fn flag_width(self, width: u16) -> LineNumbers<'a>

Required width for the flags.

pub fn margin(self, margin: (u16, u16)) -> LineNumbers<'a>

Extra margin as (left-margin, right-margin).

pub fn format(self, format: NumberFormat) -> LineNumbers<'a>

Line number format.

pub fn styles(self, styles: LineNumberStyle) -> LineNumbers<'a>

Complete set of styles.

pub fn style(self, style: Style) -> LineNumbers<'a>

Base style.

pub fn cursor_style(self, style: Style) -> LineNumbers<'a>

Style for current line.

pub fn block(self, block: Block<'a>) -> LineNumbers<'a>

Block.

pub fn width_for( start_nr: u32, flag_width: u16, margin: (u16, u16), block: u16, ) -> u16

Required width for the line-numbers.

Trait Implementations

impl<'a> Clone for LineNumbers<'a>

fn clone(&self) -> LineNumbers<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for LineNumbers<'a>

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

Formats the value using the given formatter.

impl<'a> Default for LineNumbers<'a>

fn default() -> LineNumbers<'a>

Returns the “default value” for a type.

impl StatefulWidget for LineNumbers<'_>

type State = LineNumberState

State associated with the stateful widget.

fn render( self, area: Rect, buf: &mut Buffer, state: &mut <LineNumbers<'_> as StatefulWidget>::State, )

Draws the current state of the widget in the given buffer. That is the only method required to implement a custom stateful widget.
