Struct NonZeroBigUint 

pub struct NonZeroBigUint<M>
where
    M: ManagedTypeApi,
{ /* private fields */ }

A big, unsigned number that is guaranteed not to be zero.

The restriction is enforced by the constructors and the implementation of operations.

Constructor

To build a NonZeroBigUint, the best way is via NonZeroBigUint::new(BigUint), which returns an Option:

• Some(NonZeroBigUint) if the input is non-zero, or
• None if the input is zero.

This way the user can handle the zero case as they see fit.

The quicker alternative is NonZeroBigUint::new_or_panic(BigUint), which will signal an error if the input is zero.

Binary Operators

Naturally, some operations between two NonZeroBigUint can never yield zero, so no validation is needed after those operations.

For all others, there is an additional check at the end, which will crash execution if the invariant is violated.

Specifically, for the binary operators, we have implemented:

• NonZeroBigUint + NonZeroBigUint = guaranteed non-zero, no validation needed
• NonZeroBigUint * NonZeroBigUint = guaranteed non-zero, no validation needed
• NonZeroBigUint - NonZeroBigUint = could yield zero or negative, validation needed
• NonZeroBigUint / NonZeroBigUint = could yield zero, validation needed
• NonZeroBigUint % NonZeroBigUint = could yield zero, validation needed

Assign Operators

For the assign operators, we have similar logic, but we’ve added a few more operations for convenience:

• BigUint
• u32
• u64

Again, no validation is needed when the operation guarantees a non-zero result:

• NonZeroBigUint += NonZeroBigUint
• NonZeroBigUint += &NonZeroBigUint
• NonZeroBigUint += BigUint
• NonZeroBigUint += u32
• NonZeroBigUint += u64
• NonZeroBigUint *= NonZeroBigUint
• NonZeroBigUint *= &NonZeroBigUint

Everything else gets a runtime check.

Usage in Payments

Since token payments cannot be zero, NonZeroBigUint is used in the Payment object.

Getting a call value is guaranteed to yield non-zero amounts, so in that case NonZeroBigUint is getting its invariant from the VM.

where M: ManagedTypeApi,

fn top_decode_or_handle_err<I, H>( input: I, h: H, ) -> Result<NonZeroBigUint<M>, <H as DecodeErrorHandler>::HandledErr>

where I: TopDecodeInput, H: DecodeErrorHandler,

Version of top_decode that can handle errors as soon as they occur. For instance it can exit immediately and make sure that if it returns, it is a success. By not deferring error handling, this can lead to somewhat smaller bytecode.

where I: TopDecodeInput,

Attempt to deserialize the value from input.

impl<M> TopEncode for NonZeroBigUint<M>

where M: ManagedTypeApi,

fn top_encode_or_handle_err<O, H>( &self, output: O, h: H, ) -> Result<(), <H as EncodeErrorHandler>::HandledErr>

where O: TopEncodeOutput, H: EncodeErrorHandler,

Version of top_encode that can handle errors as soon as they occur. For instance in can exit immediately and make sure that if it returns, it is a success. By not deferring error handling, this can lead to somewhat smaller bytecode.

fn top_encode<O>(&self, output: O) -> Result<(), EncodeError>

where O: TopEncodeOutput,

Attempt to serialize the value to output.

The type returned in the event of a conversion error.

fn try_from( value: u128, ) -> Result<NonZeroBigUint<M>, <NonZeroBigUint<M> as TryFrom<u128>>::Error>

Performs the conversion.

impl<M> TypeAbi for NonZeroBigUint<M>

where M: ManagedTypeApi,
