Trait Implementations

impl BorshDeserialize for MetadataUpdate

where UpdateMetadataAuthority: BorshDeserialize, UpdateKey: BorshDeserialize, RemoveKey: BorshDeserialize,

fn deserialize_reader<R: Read>(reader: &mut R) -> Result<Self, Error>

fn deserialize(buf: &mut &[u8]) -> Result<Self, Error>

Deserializes this instance from a given slice of bytes. Updates the buffer to point at the remaining bytes.

fn try_from_slice(v: &[u8]) -> Result<Self, Error>

Deserialize this instance from a slice of bytes.

fn try_from_reader<R>(reader: &mut R) -> Result<Self, Error>

where R: Read,

impl BorshSerialize for MetadataUpdate

where UpdateMetadataAuthority: BorshSerialize, UpdateKey: BorshSerialize, RemoveKey: BorshSerialize,

fn serialize<W: Write>(&self, writer: &mut W) -> Result<(), Error>

fn try_to_vec(&self) -> Result<Vec<u8>, Error>

Serialize this instance into a vector of bytes.

impl Clone for MetadataUpdate

fn clone(&self) -> MetadataUpdate

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MetadataUpdate

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

Formats the value using the given formatter.

impl EnumExt for MetadataUpdate

where UpdateMetadataAuthority: BorshDeserialize, UpdateKey: BorshDeserialize, RemoveKey: BorshDeserialize,

fn deserialize_variant<R: Read>( reader: &mut R, variant_idx: u8, ) -> Result<Self, Error>

Deserialises given variant of an enum from the reader.

impl PartialEq for MetadataUpdate

fn eq(&self, other: &MetadataUpdate) -> 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.

impl<'a> ZeroCopyAt<'a> for MetadataUpdate

type ZeroCopyAt = ZMetadataUpdate<'a>

fn zero_copy_at( data: &'a [u8], ) -> Result<(Self::ZeroCopyAt, &'a [u8]), ZeroCopyError>

impl ZeroCopyStructInner for MetadataUpdate

type ZeroCopyInner = ZMetadataUpdate<'static>
