Struct InitializeTokenMetadata 

pub struct InitializeTokenMetadata<'a> {
    pub metadata: &'a AccountView<'a>,
    pub update_authority: &'a AccountView<'a>,
    pub mint: &'a AccountView<'a>,
    pub mint_authority: &'a AccountView<'a>,
    pub name: &'a str,
    pub symbol: &'a str,
    pub uri: &'a str,
}

Initialize: write the base metadata (name, symbol, URI) into metadata, which for Token-2022 is the mint itself. The mint authority signs. The account must already hold the rent for its new size.

Fields

metadata: &'a AccountView<'a>

update_authority: &'a AccountView<'a>

mint: &'a AccountView<'a>

mint_authority: &'a AccountView<'a>

name: &'a str

symbol: &'a str

uri: &'a str

Implementations

impl InitializeTokenMetadata<'_>

pub fn invoke(&self) -> ProgramResult

Send to Token-2022.

pub fn invoke_signed(&self, signers: &[Signer<'_, '_>]) -> ProgramResult

Send to Token-2022 with PDA signers.

pub fn invoke_on_program( &self, program: &Address, signers: &[Signer<'_, '_>], ) -> ProgramResult

Send to any program that implements the interface. With no PDA signers, the instruction’s signer must have signed the transaction directly.

Trait Implementations

impl<'a, 'x: 'a> TokenInstruction<'a> for InitializeTokenMetadata<'x>

fn emit( &self, _multisig_signers: &[&'a AccountView<'a>], sink: &mut impl TokenSink<'a>, ) -> ProgramResult
