Struct gif::AnyExtension

pub struct AnyExtension(pub u8);

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.

Implementations

impl AnyExtension

pub fn into_known(self) -> Option<Extension>

Decode the label as a known extension.

Trait Implementations

impl Clone for AnyExtension

fn clone(&self) -> AnyExtension

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AnyExtension

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

Formats the value using the given formatter.

impl From<Extension> for AnyExtension

fn from(ext: Extension) -> Self

Converts to this type from the input type.

impl Hash for AnyExtension

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for AnyExtension

fn eq(&self, other: &AnyExtension) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
