Struct RawFace

pub struct RawFace<'a> {
    pub data: &'a [u8],
    pub table_records: LazyArray16<'a, TableRecord>,
}

A raw font face.

You are probably looking for Face. This is a low-level type.

Unlike Face, RawFace parses only face table records. Meaning all you can get from this type is a raw (&[u8]) data of a requested table. Then you can either parse just a singe table from a font/face or populate RawFaceTables manually before passing it to Face::from_raw_tables.

Fields

data: &'a [u8]

The input font file data.

table_records: LazyArray16<'a, TableRecord>

An array of table records.

Implementations

impl<'a> RawFace<'a>

pub fn from_slice( data: &'a [u8], index: u32, ) -> Result<RawFace<'a>, FaceParsingError>

👎Deprecated since 0.16.0: use parse instead

Creates a new RawFace from a raw data.

index indicates the specific font face in a font collection. Use fonts_in_collection to get the total number of font faces. Set to 0 if unsure.

While we do reuse FaceParsingError, No*Table errors will not be throws.

pub fn parse( data: &'a [u8], index: u32, ) -> Result<RawFace<'a>, FaceParsingError>

Creates a new RawFace from a raw data.

index indicates the specific font face in a font collection. Use fonts_in_collection to get the total number of font faces. Set to 0 if unsure.

While we do reuse FaceParsingError, No*Table errors will not be throws.

pub fn table(&self, tag: Tag) -> Option<&'a [u8]>

Returns the raw data of a selected table.
