Metadata pointer extension instructions

Variants

Initialize = 0

Initialize a new mint with a metadata pointer

Fails if the mint has already been initialized, so must be called before InitializeMint.

The mint must have exactly enough space allocated for the base mint (82 bytes), plus 83 bytes of padding, 1 byte reserved for the account type, then space required for this extension, plus any others.

Accounts expected by this instruction:

0. [writable] The mint to initialize.

Data expected by this instruction: crate::extension::metadata_pointer::instruction::InitializeInstructionData

Update = 1

Update the metadata pointer address. Only supported for mints that include the MetadataPointer extension.

Accounts expected by this instruction:

• Single authority

0. [writable] The mint.
1. [signer] The metadata pointer authority.

• Multisignature authority

0. [writable] The mint.
1. [] The mint’s metadata pointer authority.
2. ..2+M [signer] M signer accounts.

Trait Implementations

impl Clone for MetadataPointerInstruction

fn clone(&self) -> MetadataPointerInstruction

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MetadataPointerInstruction

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

Formats the value using the given formatter.

impl From<MetadataPointerInstruction> for u8

fn from(enum_value: MetadataPointerInstruction) -> Self

Converts to this type from the input type.

impl PartialEq for MetadataPointerInstruction

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

impl TryFrom<u8> for MetadataPointerInstruction

type Error = TryFromPrimitiveError<MetadataPointerInstruction>

The type returned in the event of a conversion error.

fn try_from(number: u8) -> Result<Self, TryFromPrimitiveError<Self>>

Performs the conversion.

impl TryFromPrimitive for MetadataPointerInstruction

type Primitive = u8

type Error = TryFromPrimitiveError<MetadataPointerInstruction>

const NAME: &'static str = "MetadataPointerInstruction"

fn try_from_primitive( number: Self::Primitive, ) -> Result<Self, TryFromPrimitiveError<Self>>

impl Copy for MetadataPointerInstruction
