fn from(src: AnchorFormat1) -> AnchorTable

Converts to this type from the input type.

impl From<AnchorFormat2> for AnchorTable

fn from(src: AnchorFormat2) -> AnchorTable

Converts to this type from the input type.

impl From<AnchorFormat3> for AnchorTable

fn from(src: AnchorFormat3) -> AnchorTable

Converts to this type from the input type.

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

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

impl FromTableRef<AnchorTable<'_>> for AnchorTable

fn from_table_ref(from: &T) -> Self

impl Hash for AnchorTable

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 AnchorTable

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

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

fn partial_cmp(&self, other: &AnchorTable) -> 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.

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 AnchorTable

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.
