Implementations

impl GlyphBuffer

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

Returns true if the buffer contains no elements.

pub fn glyph_infos(&self) -> &[hb_glyph_info_t]

Get the glyph infos.

pub fn glyph_positions(&self) -> &[GlyphPosition]

Get the glyph positions.

pub fn clear(self) -> UnicodeBuffer

Clears the content of the glyph buffer and returns an empty UnicodeBuffer reusing the existing allocation.

pub fn serialize(&self, face: &hb_font_t<'_>, flags: SerializeFlags) -> String

Converts the glyph buffer content into a string.
