Struct LineNumbers 

pub struct LineNumbers<U: Ui> { /* private fields */ }

Shows a column of line numbers beside the File

This can be configured through LineNumbers::cfg, in order to get, for example: relative numbering, different alignment, hidden/shown wrapped lines, etc.

Implementations

impl<U: Ui> LineNumbers<U>

pub fn absolute(&mut self) -> &mut Self

Absolute numbering, first line is 1, second is 2, etc

pub fn relative(&mut self) -> &mut Self

Relative numbering, cursor line is 0, surrounding is 1, etc

pub fn rel_abs(&mut self) -> &mut Self

A mix between relative and absolute numbering

Will show the line number of the main cursor’s line, while showing the distance to it on every other line.

pub fn align_left(&mut self) -> &mut Self

Aligns all numbers left

If you want the main line’s number to be aligned differently, call one of the align_main_* functions after this one.

pub fn align_center(&mut self) -> &mut Self

Aligns all numbers to the center

If you want the main line’s number to be aligned differently, call one of the align_main_* functions after this one.

pub fn align_right(&mut self) -> &mut Self

Aligns all numbers right

If you want the main line’s number to be aligned differently, call one of the align_main_* functions after this one.

pub fn align_main_left(&mut self) -> &mut Self

Aligns onle the main line’s number to the left

pub fn align_main_center(&mut self) -> &mut Self

Aligns onle the main line’s number to the center

pub fn align_main_right(&mut self) -> &mut Self

Aligns onle the main line’s number to the right

pub fn show_wraps(&mut self) -> &mut Self

Shows wrapping lines, is false by default

pub fn hide_wraps(&mut self) -> &mut Self

Hides wrapping lines, is true by default
