Struct UpdateMetadataField 

pub struct UpdateMetadataField<'a> {
    pub metadata: &'a AccountView<'a>,
    pub update_authority: &'a AccountView<'a>,
    pub field: MetadataField<'a>,
    pub value: &'a str,
}

UpdateField: set the name, the symbol, the URI, or an additional key to value. A new key or a longer value grows the account, which must already hold the rent for it.

Fields

metadata: &'a AccountView<'a>

update_authority: &'a AccountView<'a>

field: MetadataField<'a>

value: &'a str

Implementations

impl UpdateMetadataField<'_>

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.
