Struct NotPayable

pub struct NotPayable;

Transaction marker, which indicates that a transaction should never have any payment added to it.

The implementation is completely identical to the empty payment (), the only difference is that the payment methods in Tx can only be called on top of () payment, not NotPayable.

So basically, NotPayable acts as a seal, preventing further payments to be added.

Trait Implementations

impl<Env> AnnotatedValue<Env, BigUint<<Env as TxEnv>::Api>> for NotPayable

where Env: TxEnv,

fn annotation(&self, _env: &Env) -> ManagedBuffer<Env::Api>

fn to_value(&self, _env: &Env) -> BigUint<Env::Api>

Produces the value from a reference of the annotated type. Might involve a .clone() in some cases.

fn into_value(self, env: &Env) -> T

Consumes annotated value to produce actual value.

fn with_value_ref<F, R>(&self, env: &Env, f: F) -> R

where F: FnOnce(&T) -> R,

Can be used when working with references only.

impl<Env> TxPayment<Env> for NotPayable

where Env: TxEnv,

fn is_no_payment(&self, _env: &Env) -> bool

Returns true if payment indicates transfer of either non-zero EGLD or ESDT amounts.

fn perform_transfer_execute( self, env: &Env, to: &ManagedAddress<Env::Api>, gas_limit: u64, fc: FunctionCall<Env::Api>, )

Transfer-execute calls have different APIs for different payments types. This method selects between them.

fn with_normalized<From, To, F, R>( self, env: &Env, from: &From, to: To, fc: FunctionCall<Env::Api>, f: F, ) -> R

where From: TxFrom<Env>, To: TxToSpecified<Env>, F: FnOnce(&ManagedAddress<Env::Api>, &BigUint<Env::Api>, FunctionCall<Env::Api>) -> R,

Converts an ESDT call to a built-in function call, if necessary.

fn into_full_payment_data(self, _env: &Env) -> FullPaymentData<Env::Api>

Payment data to be used by the testing framework. Will be refactored.

impl<Env> TxPaymentEgldOnly<Env> for NotPayable

where Env: TxEnv,

fn with_egld_value<F, R>(&self, env: &Env, f: F) -> R

where F: FnOnce(&BigUint<Env::Api>) -> R,

fn into_egld_payment(self, env: &Env) -> BigUint<Env::Api>

impl<Env> TxNoPayment<Env> for NotPayable

where Env: TxEnv,
