Struct GlyphBuffer

source
pub struct GlyphBuffer(/* private fields */);
Expand description

A buffer that contains the results of the shaping process.

Implementations§

source§

impl GlyphBuffer

source

pub fn len(&self) -> usize

Returns the length of the data of the buffer.

When called before shaping this is the number of unicode codepoints contained in the buffer. When called after shaping it returns the number of glyphs stored.

source

pub fn is_empty(&self) -> bool

Returns true if the buffer contains no elements.

source

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

Get the glyph infos.

source

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

Get the glyph positions.

source

pub fn clear(self) -> UnicodeBuffer

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

source

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

Converts the glyph buffer content into a string.
