Struct UiAmountToAmount 

pub struct UiAmountToAmount<'a> {
    pub mint: &'a AccountView<'a>,
    pub ui_amount: &'a str,
}

UiAmountToAmount (24): parse a decimal string against the mint and return the raw amount as a u64 in the return data. Read it with return_data_u64. Strings longer than MAX_UI_AMOUNT_LEN bytes are refused before the CPI.

Fields

mint: &'a AccountView<'a>

ui_amount: &'a str

Implementations

impl UiAmountToAmount<'_>

pub fn invoke(&self) -> ProgramResult

pub fn query(&self, program: TokenProgram) -> Result<u64, ProgramError>

Invoke on program and read the raw amount from the return data.

impl UiAmountToAmount<'_>

pub fn invoke_on( &self, program: TokenProgram, multisig_signers: &[&AccountView<'_>], signers: &[Signer<'_, '_>], ) -> ProgramResult

Send this instruction to an explicit token program.

multisig_signers is empty for a single-key authority; when signers is empty the authority (or every multisig signer) must have signed the transaction directly.

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

Send this instruction to whichever token program owns mint (one 32-byte compare). Any other owner is refused with IncorrectProgramId before the CPI.
