Struct gif::AnyExtension

pub struct AnyExtension(pub u8);

[−] Expand description

A newtype wrapper around an arbitrary extension ID.

An extension is some amount of byte data organized in sub-blocks so that one can skip over it without knowing the semantics. Though technically you likely want to use a Application extension, the library tries to stay flexible here.

This allows us to customize the set of impls compared to a raw u8. It also clarifies the intent and gives some inherent methods for interoperability with known extension types.
