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 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: &Self) -> 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.
