Implementations

impl ApproveChecked<'_>

pub fn invoke(&self) -> ProgramResult

pub fn invoke_strict(&self) -> ProgramResult

Strict invoke: signer pre-check plus source-account ownership verification. Ensures the authority granting the approval is actually allowed to do so. See TransferChecked::invoke_strict for the full rationale.

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

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

Strict PDA-signed invoke. Pre-check the source-account owner before the CPI.
