Struct BurnChecked 

pub struct BurnChecked<'a> {
    pub account: &'a AccountView,
    pub mint: &'a AccountView,
    pub authority: &'a AccountView,
    pub amount: u64,
    pub decimals: u8,
}

Builder for SPL Token BurnChecked (instruction index 15).

Decimals-verified counterpart to [Burn]. Prefer this over Burn whenever the mint’s decimals are known to the caller, so the SPL token program can reject a mis-routed call at CPI time.

Fields

account: &'a AccountView

mint: &'a AccountView

authority: &'a AccountView

amount: u64

decimals: u8

Implementations

impl BurnChecked<'_>

pub fn invoke(&self) -> ProgramResult

pub fn invoke_strict(&self) -> ProgramResult

Strict invoke: signer pre-check plus token-account ownership verification. 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 burn-source owner before the CPI so a misrouted signer surfaces a Hopper-branded error instead of an opaque SPL failure.
