Struct piet::HitTestPosition

source ·
#[non_exhaustive]
pub struct HitTestPosition { pub point: Point, pub line: usize, }
Expand description

Result of hit testing a text position in a TextLayout.

This type is returned by TextLayout::hit_test_text_position.

Fields (Non-exhaustive)§

This struct is marked as non-exhaustive
Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.
§point: Point

the point’s x value is the position of the leading edge of the grapheme cluster containing the text position. The y value corresponds to the baseline of the line containing that grapheme cluster.

§line: usize

The number of the line containing this position.

This value can be used to retrieve the LineMetric for this line, via the TextLayout::line_metric method.
