}

A trait for types to which an incremental font transfer patch can be applied.

See: https://w3c.github.io/IFT/Overview.html#font-patch-formats for details on the format of patches.

Required Methods

fn apply_table_keyed_patch<D: SharedBrotliDecoder>( &self, patch: &PatchInfo, patch_data: &[u8], brotli_decoder: &D, ) -> Result<Vec<u8>, PatchingError>

Apply a table keyed incremental font patches (https://w3c.github.io/IFT/Overview.html#font-patch-formats)

Applies the patches to this base.

Returns the byte data for the new font produced as a result of the patch applications.

fn apply_glyph_keyed_patches<'a, D: SharedBrotliDecoder>( &self, patches: impl Iterator<Item = (&'a PatchInfo, &'a [u8])>, brotli_decoder: &D, ) -> Result<Vec<u8>, PatchingError>

Apply a set of glyph keyed incremental font patches (https://w3c.github.io/IFT/Overview.html#font-patch-formats)

Applies the patches to this base.

Returns the byte data for the new font produced as a result of the patch applications.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
