Struct casper_types::contracts::ContractPackageHash

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

A newtype wrapping a HashAddr which references a ContractPackage in the global state.

Implementations

impl ContractPackageHash

pub const fn new(value: HashAddr) -> ContractPackageHash

Constructs a new ContractPackageHash from the raw bytes of the contract package hash.

pub fn value(&self) -> HashAddr

Returns the raw bytes of the contract hash as an array.

pub fn as_bytes(&self) -> &[u8]

Returns the raw bytes of the contract hash as a slice.

pub fn to_formatted_string(self) -> String

Formats the ContractPackageHash for users getting and putting.

pub fn from_formatted_str(input: &str) -> Result<Self, FromStrError>

Parses a string formatted as per Self::to_formatted_string() into a ContractPackageHash.

Trait Implementations

impl Clone for ContractPackageHash

fn clone(&self) -> ContractPackageHash

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ContractPackageHash

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

Formats the value using the given formatter.

impl Default for ContractPackageHash

fn default() -> ContractPackageHash

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ContractPackageHash

fn deserialize<D: Deserializer<'de>>(deserializer: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl Display for ContractPackageHash

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

Formats the value using the given formatter.

impl From<[u8; 32]> for ContractPackageHash

fn from(bytes: [u8; 32]) -> Self

Converts to this type from the input type.

impl From<ContractPackageHash> for Key

fn from(package_hash: ContractPackageHash) -> Key

Converts to this type from the input type.

impl FromBytes for ContractPackageHash

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 Hash for ContractPackageHash

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 Ord for ContractPackageHash

fn cmp(&self, other: &ContractPackageHash) -> 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,

Restrict a value to a certain interval.

impl PartialEq for ContractPackageHash

fn eq(&self, other: &ContractPackageHash) -> 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 for ContractPackageHash

fn partial_cmp(&self, other: &ContractPackageHash) -> 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 ContractPackageHash

fn serialize<S: Serializer>(&self, serializer: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.

impl ToBytes for ContractPackageHash

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>.

impl TryFrom<&[u8]> for ContractPackageHash

type Error = TryFromSliceForContractHashError

The type returned in the event of a conversion error.

fn try_from(bytes: &[u8]) -> Result<Self, TryFromSliceForContractHashError>

Performs the conversion.

impl TryFrom<&Vec<u8>> for ContractPackageHash

type Error = TryFromSliceForContractHashError

The type returned in the event of a conversion error.

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

Performs the conversion.
