Struct ContractHash

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

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

Implementations

impl ContractHash

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

Constructs a new ContractHash from the raw bytes of the contract 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 ContractHash 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 ContractHash.

Trait Implementations

impl AsRef<[u8]> for ContractHash

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl CLTyped for ContractHash

fn cl_type() -> CLType

The CLType of Self.

impl Clone for ContractHash

fn clone(&self) -> ContractHash

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl DataSize for ContractHash

const IS_DYNAMIC: bool = false

If true, the type has a heap size that can vary at runtime, depending on the actual value.

const STATIC_HEAP_SIZE: usize = 0usize

The amount of space a value of the type always occupies. If IS_DYNAMIC is false, this is the total amount of heap memory occupied by the value. Otherwise this is a lower bound.

fn estimate_heap_size(&self) -> usize

Estimates the size of heap memory taken up by this value.

impl Debug for ContractHash

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

Formats the value using the given formatter.

impl Default for ContractHash

fn default() -> ContractHash

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ContractHash

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

Deserialize this value from the given Serde deserializer.

impl Display for ContractHash

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

Formats the value using the given formatter.

impl From<[u8; 32]> for ContractHash

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

Converts to this type from the input type.

impl From<AddressableEntityHash> for ContractHash

fn from(entity_hash: AddressableEntityHash) -> Self

Converts to this type from the input type.

impl From<ContractHash> for AddressableEntityHash

fn from(contract_hash: ContractHash) -> Self

Converts to this type from the input type.

impl From<ContractHash> for Key

fn from(contract_hash: ContractHash) -> Self

Converts to this type from the input type.

impl FromBytes for ContractHash

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 ContractHash

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 JsonSchema for ContractHash

Available on crate feature json-schema only.

fn schema_name() -> String

The name of the generated JSON Schema.

fn json_schema(gen: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn is_referenceable() -> bool

Whether JSON Schemas generated for this type should be re-used where possible using the $ref keyword.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

impl Ord for ContractHash

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

fn eq(&self, other: &ContractHash) -> 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 ContractHash

fn partial_cmp(&self, other: &ContractHash) -> 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.

impl Serialize for ContractHash

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

Serialize this value into the given Serde serializer.

impl ToBytes for ContractHash

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,

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

Performs the conversion.

impl TryFrom<&Vec<u8>> for ContractHash

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.
