Struct write_fonts::tables::cmap::Cmap

pub struct Cmap {
    pub encoding_records: Vec<EncodingRecord>,
}

cmap

Fields

encoding_records: Vec<EncodingRecord>

Implementations

impl Cmap

pub fn new(encoding_records: Vec<EncodingRecord>) -> Self

Construct a new Cmap

impl Cmap

pub fn from_mappings( mappings: impl IntoIterator<Item = (char, GlyphId)> ) -> Cmap

Generates a cmap that is expected to work in most modern environments.

For the time being just emits format 4 so we can drive towards compiling working fonts. In time we may wish to additionally emit format 12 to support novel codepoints.

Trait Implementations

impl Clone for Cmap

fn clone(&self) -> Cmap

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Cmap

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

Formats the value using the given formatter.

impl Default for Cmap

fn default() -> Cmap

Returns the “default value” for a type.

impl<'a> FontRead<'a> for Cmap

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

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

impl FontWrite for Cmap

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 Hash for Cmap

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 Cmap

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<Cmap> for Cmap

fn eq(&self, other: &Cmap) -> 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<Cmap> for Cmap

fn partial_cmp(&self, other: &Cmap) -> 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 TopLevelTable for Cmap

const TAG: Tag = _

The table’s tag.

impl Validate for Cmap

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 Cmap

impl StructuralEq for Cmap

impl StructuralPartialEq for Cmap
