Struct EmitTokenMetadata 

pub struct EmitTokenMetadata<'a> {
    pub metadata: &'a AccountView<'a>,
    pub start: Option<u64>,
    pub end: Option<u64>,
}

Emit: return the serialized metadata (or the start..end slice of it) as the program’s return data.

Fields

metadata: &'a AccountView<'a>

start: Option<u64>

end: Option<u64>

Implementations

impl EmitTokenMetadata<'_>

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.
