Struct ReservationNonce 

pub struct ReservationNonce(/* private fields */);

An unchangeable wrapper over u64 value, which is required to be used as a “view-only” reservations nonce in a message execution context.

Note:

By contract, It must be instantiated only once, when message execution context is created. Also the latter is required to be instantiated only once, when incoming dispatch is created.

Trait Implementations

fn decode_as_fields<'info, R: TypeResolver>( input: &mut &[u8], fields: &mut dyn FieldIter<'info, R::TypeId>, types: &'info R, ) -> Result<Self, Error>

Given some bytes and some fields denoting their structure, attempt to decode.

impl Default for ReservationNonce

fn default() -> ReservationNonce

Returns the “default value” for a type.

impl Encode for ReservationNonce

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

fn encode_to<__CodecOutputEdqy: Output + ?Sized>( &self, __codec_dest_edqy: &mut __CodecOutputEdqy, )

Convert self to a slice and append it to the destination.

fn encode(&self) -> Vec<u8>

fn using_encoded<__CodecOutputReturn, __CodecUsingEncodedCallback: FnOnce(&[u8]) -> __CodecOutputReturn>( &self, f: __CodecUsingEncodedCallback, ) -> __CodecOutputReturn

Convert self to a slice and then invoke the given closure with it.

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl EncodeAsFields for ReservationNonce

fn encode_as_fields_to<ScaleEncodeResolver: TypeResolver>( &self, __encode_as_type_fields: &mut dyn FieldIter<'_, ScaleEncodeResolver::TypeId>, __encode_as_type_types: &ScaleEncodeResolver, __encode_as_type_out: &mut Vec<u8>, ) -> Result<(), Error>

where R: TypeResolver,

This is a helper function which internally calls EncodeAsFields::encode_as_fields_to. Prefer to implement that instead.

impl EncodeAsType for ReservationNonce

fn encode_as_type_to<ScaleEncodeResolver: TypeResolver>( &self, __encode_as_type_type_id: ScaleEncodeResolver::TypeId, __encode_as_type_types: &ScaleEncodeResolver, __encode_as_type_out: &mut Vec<u8>, ) -> Result<(), Error>

Given some type_id, types, a context and some output target for the SCALE encoded bytes, attempt to SCALE encode the current value into the type given by type_id.

fn encode_as_type<R>( &self, type_id: <R as TypeResolver>::TypeId, types: &R, ) -> Result<Vec<u8>, Error>

where R: TypeResolver,

This is a helper function which internally calls EncodeAsType::encode_as_type_to. Prefer to implement that instead.

impl EncodeLike for ReservationNonce

impl Eq for ReservationNonce

impl Hash for ReservationNonce

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl IntoVisitor for ReservationNonce

type AnyVisitor<ScaleDecodeTypeResolver: TypeResolver> = Visitor<ScaleDecodeTypeResolver>

The visitor type used to decode SCALE encoded bytes to Self.

fn into_visitor<ScaleDecodeTypeResolver: TypeResolver>() -> Self::AnyVisitor<ScaleDecodeTypeResolver>

A means of obtaining this visitor.

impl Ord for ReservationNonce

fn cmp(&self, other: &ReservationNonce) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for ReservationNonce

fn eq(&self, other: &ReservationNonce) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for ReservationNonce

fn partial_cmp(&self, other: &ReservationNonce) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
