cmap Format 2: High-byte mapping through table

Fields

length: u16

This is the length in bytes of the subtable.

language: u16

For requirements on use of the language field, see “Use of the language field in ‘cmap’ subtables” in this document.

sub_header_keys: Vec<u16>

Array that maps high bytes to subHeaders: value is subHeader index × 8.

Implementations

impl Cmap2

pub fn new(length: u16, language: u16, sub_header_keys: Vec<u16>) -> Self

Construct a new Cmap2

Trait Implementations

impl Clone for Cmap2

fn clone(&self) -> Cmap2

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Cmap2

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

Formats the value using the given formatter.

impl Default for Cmap2

fn default() -> Cmap2

Returns the “default value” for a type.

impl<'a> FontRead<'a> for Cmap2

fn read(data: FontData<'a>) -> Result<Self, ReadError>

Read an instace of Self from the provided data, performing validation.

impl FontWrite for Cmap2

fn write_into(&self, writer: &mut TableWriter)

Write our data and information about offsets into this TableWriter.

fn table_type(&self) -> TableType

The type of this table.

impl From<Cmap2> for CmapSubtable

fn from(src: Cmap2) -> CmapSubtable

Converts to this type from the input type.

impl Hash for Cmap2

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Cmap2

fn cmp(&self, other: &Cmap2) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for Cmap2

fn eq(&self, other: &Cmap2) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for Cmap2

fn partial_cmp(&self, other: &Cmap2) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Validate for Cmap2

fn validate_impl(&self, _ctx: &mut ValidationCtx)

Validate this table.

fn validate(&self) -> Result<(), ValidationReport>

Ensure that this table is well-formed, reporting any errors.

impl Eq for Cmap2
