Struct LineBoundary 

pub struct LineBoundary { /* private fields */ }

A TextBoundary subclass for locating closest line breaks to a given position.

When the given position points to a hard line break, the returned range is the line’s content range before the hard line break, and does not contain the given position. For instance, the line breaks at position = 1 for “a\nb” is [0, 1), which does not contain the position 1.
