Struct ScriptList 

pub struct ScriptList<'a> { /* private fields */ }

Script List Table

Implementations

impl<'a> ScriptList<'a>

pub fn index_for_tag(&self, tag: Tag) -> Option<u16>

Returns the index of the script with the given tag.

pub fn get(&self, index: u16) -> Result<TaggedElement<Script<'a>>, ReadError>

Returns the tag and script at the given index.

pub fn select(&self, tags: &[Tag]) -> Option<SelectedScript>

Finds the first available script that matches one of the given tags.

When none of the requested scripts are available, then DFLT, dflt and latn tags are tried in that order.

If you’re starting from a Unicode script code, use the ScriptTags::from_unicode function to generate the appropriate set of tags to pass to this method.

See hb_ot_layout_table_select_script for the corresponding HarfBuzz function.

impl<'a> ScriptList<'a>

pub const MIN_SIZE: usize = u16::RAW_BYTE_LEN

pub fn resolve_offset<O: Offset, R: FontRead<'a>>( &self, offset: O, ) -> Result<R, ReadError>

Resolve the provided offset from the start of this table.

pub fn offset_data(&self) -> FontData<'a>

Return a reference to this table’s raw data.

We use this in the compile crate to resolve offsets.

pub fn shape(&self) -> &Self

👎Deprecated:

just use the base type directly

Return a reference to the table’s ‘Shape’ struct.

This is a low level implementation detail, but it can be useful in some cases where you want to know things about a table’s layout, such as the byte offsets of specific fields.

pub fn script_count(&self) -> u16

Number of ScriptRecords

pub fn script_records(&self) -> &'a [ScriptRecord]

Array of ScriptRecords, listed alphabetically by script tag

pub fn script_count_byte_range(&self) -> Range<usize>

pub fn script_records_byte_range(&self) -> Range<usize>

Trait Implementations

impl<'a> Clone for ScriptList<'a>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> FontRead<'a> for ScriptList<'a>

fn read(data: FontData<'a>) -> Result<Self, ReadError>

Read an instance of Self from the provided data, performing validation.

impl<'a> MinByteRange<'a> for ScriptList<'a>

fn min_byte_range(&self) -> Range<usize>

fn min_table_bytes(&self) -> &'a [u8]
