Transfer hook extension instructions

Variants

Initialize = 0

Initialize a new mint with a transfer hook program.

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::transfer_hook::instruction::InitializeInstructionData

Update = 1

Update the transfer hook program id. Only supported for mints that include the TransferHook extension.

Accounts expected by this instruction:

• Single authority

0. [writable] The mint.
1. [signer] The transfer hook authority.

• Multisignature authority

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

Data expected by this instruction: crate::extension::transfer_hook::UpdateInstructionData

Trait Implementations

impl Clone for TransferHookInstruction

fn clone(&self) -> TransferHookInstruction

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TransferHookInstruction

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

Formats the value using the given formatter.

impl From<TransferHookInstruction> for u8

fn from(enum_value: TransferHookInstruction) -> Self

Converts to this type from the input type.

impl PartialEq for TransferHookInstruction

fn eq(&self, other: &TransferHookInstruction) -> 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 TransferHookInstruction

type Error = TryFromPrimitiveError<TransferHookInstruction>

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 TransferHookInstruction

type Primitive = u8

type Error = TryFromPrimitiveError<TransferHookInstruction>

const NAME: &'static str = "TransferHookInstruction"

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