Enum WordWrap 

pub enum WordWrap {
    Off,
    Viewport,
    Column(u32),
    Bounded(u32),
}

Where a code editor breaks a line too long for it onto the rows below.

A broken line is still one line of the document: its number is drawn on its first row only, Up, Down, Home and End follow the rows, and the lines on screen are reported as the document’s own. A line breaks after the last space that fits, or where a word is longer than the row, at the column itself.

Variants

Off

No line breaks; a long line runs past the edge.

Viewport

At the edge of the view.

Column(u32)

At this many columns, whatever the width of the view.

Bounded(u32)

At this many columns, or at the edge of the view where that comes first.

Implementations

impl WordWrap

pub fn to_value(self) -> i64

The integer the WordWrap property carries: the WordWrapMode tag in the low 16 bits and the column count above them.

pub fn from_value(value: i64) -> Option<Self>

Reads back what WordWrap::to_value wrote, or None where the mode is not one, the value is below zero, or a mode that counts columns counts none.
