Struct OptionalRegistry

pub struct OptionalRegistry<T: Registry>(/* private fields */);

A registry that might not be present. This is transmitted as a single varint in the protocol.

Trait Implementations

impl<T: Clone + Registry> Clone for OptionalRegistry<T>

fn clone(&self) -> OptionalRegistry<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug + Registry> Debug for OptionalRegistry<T>

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

Formats the value using the given formatter.

impl<T: Hash + Registry> Hash for OptionalRegistry<T>

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<T: Registry> McBufReadable for OptionalRegistry<T>

fn read_from(buf: &mut Cursor<&[u8]>) -> Result<Self, BufReadError>

impl<T: Registry> McBufWritable for OptionalRegistry<T>

fn write_into(&self, buf: &mut impl Write) -> Result<(), Error>

impl<T: PartialEq + Registry> PartialEq for OptionalRegistry<T>

fn eq(&self, other: &OptionalRegistry<T>) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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