Struct casper_types::contracts::ContractVersionKey

pub struct ContractVersionKey(_, _);

Major element of ProtocolVersion combined with ContractVersion.

Implementations

impl ContractVersionKey

pub fn new( protocol_version_major: ProtocolVersionMajor, contract_version: ContractVersion ) -> Self

Returns a new instance of ContractVersionKey with provided values.

pub fn protocol_version_major(self) -> ProtocolVersionMajor

Returns the major element of the protocol version this contract is compatible with.

pub fn contract_version(self) -> ContractVersion

Returns the contract version within the protocol major version.

Trait Implementations

impl Clone for ContractVersionKey

fn clone(&self) -> ContractVersionKey

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ContractVersionKey

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for ContractVersionKey

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<ContractVersionKey> for (ProtocolVersionMajor, ContractVersion)

fn from(contract_version_key: ContractVersionKey) -> Self

Converts to this type from the input type.

impl FromBytes for ContractVersionKey

fn from_bytes(bytes: &[u8]) -> Result<(Self, &[u8]), Error>

Deserializes the slice into Self.

fn from_vec(bytes: Vec<u8>) -> Result<(Self, Vec<u8>), Error>

Deserializes the Vec<u8> into Self.

impl Ord for ContractVersionKey

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<ContractVersionKey> for ContractVersionKey

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd<ContractVersionKey> for ContractVersionKey

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl Serialize for ContractVersionKey

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where __S: Serializer,

Serialize this value into the given Serde serializer.

impl ToBytes for ContractVersionKey

fn to_bytes(&self) -> Result<Vec<u8>, Error>

Serializes &self to a Vec<u8>.

fn serialized_length(&self) -> usize

Returns the length of the Vec<u8> which would be returned from a successful call to to_bytes() or into_bytes(). The data is not actually serialized, so this call is relatively cheap.

fn write_bytes(&self, writer: &mut Vec<u8>) -> Result<(), Error>

Writes &self into a mutable writer.

fn into_bytes(self) -> Result<Vec<u8>, Error>where Self: Sized,

Consumes self and serializes to a Vec<u8>.
