Enum FontReader 

#[non_exhaustive]
pub enum FontReader<'a> {
    OpenType(OpenTypeReader<'a>),
    Woff2(Woff2Reader),
}

Generic font reader that auto-detects the file format based on its first bytes.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

OpenType(OpenTypeReader<'a>)

OpenType reader.

Woff2(Woff2Reader)

Available on crate feature woff2 only.

WOFF2 reader.

Implementations

impl<'a> FontReader<'a>

pub fn new(bytes: &'a [u8]) -> Result<Self, ParseError>

Creates a reader.

Errors

Returns parsing errors if any are encountered. This includes the case when the file format cannot be detected.

pub fn format(&self) -> FileFormat

Returns the font format.

pub fn raw_tables( &self, ) -> impl ExactSizeIterator<Item = (TableTag, &[u8])> + '_

Iterates over all tables in the file (including ones that are not processed by Font).

pub fn read(&self) -> Result<Font<'_>, ParseError>

Reads a Font from this reader. The font may borrow data from this reader.

Errors

Returns parsing errors (e.g., on missing required tables).

Trait Implementations

impl<'a> Clone for FontReader<'a>

fn clone(&self) -> FontReader<'a>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for FontReader<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
