Struct Table

pub struct Table<'a> {
    pub axes: LazyArray16<'a, AxisRecord>,
    pub fallback_name_id: Option<u16>,
    /* private fields */
}

A Style Attributes Table.

Fields

axes: LazyArray16<'a, AxisRecord>

List of axes

fallback_name_id: Option<u16>

Fallback name when everything can be elided.

Implementations

impl<'a> Table<'a>

pub fn parse(data: &'a [u8]) -> Option<Self>

Parses a table from raw data.

pub fn subtables(&self) -> AxisValueSubtables<'a>

Returns an iterator over the collection of axis value tables.

pub fn subtable_for_axis( &self, axis: Tag, match_value: Option<Fixed>, ) -> Option<AxisValueSubtable<'_>>

Returns the first matching subtable for a given axis.

If no match value is given the first subtable for the axis is returned. If a match value is given, the first subtable for the axis where the value matches is returned. A value matches if it is equal to the subtable’s value or contained within the range defined by the subtable. If no matches are found None is returned. Typically a match value is not specified for non-variable fonts as multiple subtables for a given axis ought not exist. For variable fonts a non-None match value should be specified as multiple records for each of the variation axes exist.

Note: Format 4 subtables are explicitly ignored in this function.

Trait Implementations

impl<'a> Clone for Table<'a>

fn clone(&self) -> Table<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Table<'a>

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

Formats the value using the given formatter.
