Lookup Table

Fields

lookup_flag: LookupFlag

Lookup qualifiers

subtables: Vec<OffsetMarker<T>>

Array of offsets to lookup subtables, from beginning of Lookup table

mark_filtering_set: u16

Index (base 0) into GDEF mark glyph sets structure. This field is only present if the USE_MARK_FILTERING_SET lookup flag is set.

Implementations

impl<T> Lookup<T>

pub fn new( lookup_flag: LookupFlag, subtables: Vec<T>, mark_filtering_set: u16 ) -> Self

Construct a new Lookup

impl Lookup<SequenceContext>

Trait Implementations

impl<T: Clone> Clone for Lookup<T>

fn clone(&self) -> Lookup<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Lookup<T>

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

Formats the value using the given formatter.

impl<T: Default> Default for Lookup<T>

fn default() -> Lookup<T>

Returns the “default value” for a type.

impl<T: LookupSubtable + FontWrite> FontWrite for Lookup<T>

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<T: Hash> Hash for Lookup<T>

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<T: Ord> Ord for Lookup<T>

fn cmp(&self, other: &Lookup<T>) -> 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<T: PartialEq> PartialEq for Lookup<T>

fn eq(&self, other: &Lookup<T>) -> 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<T: PartialOrd> PartialOrd for Lookup<T>

fn partial_cmp(&self, other: &Lookup<T>) -> 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<T: RemapVariationIndices> RemapVariationIndices for Lookup<T>

fn remap_variation_indices(&mut self, key_map: &VariationIndexRemapping)

Remap any TemporaryDeltaSetIds to their final VariationIndex values

impl<T: Validate> Validate for Lookup<T>

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.
