Expand description

Paragraph Cursor

Fields§

§paragraph: usize

0 is first paragraph, and so on. Note that a single paragraph can span multiple rows. (a paragraph is text separated by \n).

§offset: usize

Character based (NOT bytes). It is fine if this points to something beyond the end of the current paragraph. When moving up/down it may again be within the next paragraph.

§prefer_next_row: bool

If this cursors sits right at the border of a wrapped row break (NOT paragraph break) do we prefer the next row? This is almost always what you want, except for when explicitly clicking the end of a row or pressing the end key.

source§

impl PartialEq<PCursor> for PCursor

Two PCursors are considered equal if they refer to the same character boundary, even if one prefers the start of the next row.

source§

fn eq(&self, other: &PCursor) -> bool

This method tests for self and other values to be equal, and is used by ==.
1.0.0 · source§

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
