Implementations

impl<'a> FieldType<'a>

pub fn array_of_records<T>( type_name: &'static str, records: &'a [T], data: FontData<'a> ) -> FieldType<'a>

where T: Clone + SomeRecord<'a> + 'a,

makes a field, handling the case where this array may not be present in all versions

pub fn computed_array<T>( type_name: &'static str, array: ComputedArray<'a, T>, data: FontData<'a> ) -> FieldType<'a>

where T: FontReadWithArgs<'a> + ComputeSize + SomeRecord<'a> + 'a, T::Args: Copy + 'static,

pub fn var_array<T>( type_name: &'static str, array: VarLenArray<'a, T>, data: FontData<'a> ) -> FieldType<'a>

where T: FontRead<'a> + VarSize + SomeRecord<'a> + 'a,

pub fn array_of_offsets<O>( type_name: &'static str, offsets: &'a [O], resolver: impl Fn(&O) -> FieldType<'a> + 'a ) -> Self

Convenience method for creating a FieldType from an array of offsets.

The resolver argument is a function that takes an offset and resolves it.

pub fn offset_to_array_of_scalars<T: SomeArray<'a> + 'a>( offset: impl Into<OffsetType>, result: impl Into<Option<Result<T, ReadError>>> ) -> Self

Convenience method for creating a FieldType from an offset to an array.

pub fn offset_to_array_of_records<T: Clone + SomeRecord<'a> + 'a>( offset: impl Into<OffsetType>, result: impl Into<Option<Result<&'a [T], ReadError>>>, type_name: &'static str, data: FontData<'a> ) -> Self

Convenience method for creating a FieldType from an offset to an array.

pub fn offset<T: SomeTable<'a> + 'a>( offset: impl Into<OffsetType>, result: impl Into<Option<Result<T, ReadError>>> ) -> Self

Convenience method for creating a FieldType for a resolved offset.

This handles cases where offsets are nullable, in which case the result argument may be None.

pub fn unknown_offset(offset: impl Into<OffsetType>) -> Self

Convenience method for creating a FieldType from an unknown offset.
