fn table_type(&self) -> TableType

The type of this table.

impl From<SingleSubstFormat1> for SingleSubst

fn from(src: SingleSubstFormat1) -> SingleSubst

Converts to this type from the input type.

impl From<SingleSubstFormat2> for SingleSubst

fn from(src: SingleSubstFormat2) -> SingleSubst

Converts to this type from the input type.

impl FromObjRef<SingleSubst<'_>> for SingleSubst

fn from_obj_ref(obj: &SingleSubst<'_>, _: FontData<'_>) -> Self

Convert from to an instance of Self, using the provided data to resolve offsets.

impl FromTableRef<SingleSubst<'_>> for SingleSubst

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 LookupSubtable for SingleSubst

const TYPE: LookupType = _

The lookup type of this layout subtable.

impl Ord for SingleSubst

fn cmp(&self, other: &SingleSubst) -> 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 SingleSubst

fn eq(&self, other: &SingleSubst) -> 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.

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.
