Struct composable::views::text::Glyphs

pub struct Glyphs(/* private fields */);
Available on crate features unstable and views only.
Expand description

A buffer that contains the results of the shaping process.

Implementations§

§

impl GlyphBuffer

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.

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.
