Struct piecrust::ContractId

#[repr(C)]
pub struct ContractId(/* private fields */);

ID to identify the wasm contracts after they have been deployed

Implementations

impl ContractId

pub const fn uninitialized() -> ContractId

Creates a placeholder ContractId until the host deploys the contract and sets a real ContractId. This can also be used to determine if a contract is the first to be called.

pub const fn from_bytes(bytes: [u8; 32]) -> ContractId

Creates a new ContractId from an array of bytes

pub const fn to_bytes(self) -> [u8; 32]

Returns the array of bytes that make up the ContractId

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

Returns a reference to the array of bytes that make up the ContractId

pub fn as_bytes_mut(&mut self) -> &mut [u8]

Returns a mutable reference to the array of bytes that make up the ContractId

pub fn is_uninitialized(&self) -> bool

Determines whether the ContractId is uninitialized, which can be used to check if this contract is the first to be called.

Trait Implementations

impl Archive for ContractId

where [u8; 32]: Archive,

type Archived = ContractId

The archived representation of this type.

type Resolver = ContractIdResolver

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.

unsafe fn resolve( &self, pos: usize, resolver: <ContractId as Archive>::Resolver, out: *mut <ContractId as Archive>::Archived )

Creates the archived version of this value at the given position and writes it to the given output.

impl AsMut<[u8]> for ContractId

fn as_mut(&mut self) -> &mut [u8]

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

impl AsRef<[u8]> for ContractId

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

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

impl<__C> CheckBytes<__C> for ContractId

where [u8; 32]: CheckBytes<__C>, __C: ?Sized,

type Error = TupleStructCheckError

The error that may result from checking the type.

unsafe fn check_bytes<'__bytecheck>( value: *const ContractId, context: &mut __C ) -> Result<&'__bytecheck ContractId, TupleStructCheckError>

Checks whether the given pointer points to a valid value within the given context.

impl Clone for ContractId

fn clone(&self) -> ContractId

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ContractId

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

Formats the value using the given formatter.

impl<__D> Deserialize<ContractId, __D> for <ContractId as Archive>::Archived

where __D: Fallible + ?Sized, [u8; 32]: Archive, <[u8; 32] as Archive>::Archived: Deserialize<[u8; 32], __D>,

fn deserialize( &self, deserializer: &mut __D ) -> Result<ContractId, <__D as Fallible>::Error>

Deserializes using the given deserializer

impl Display for ContractId

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

Formats the value using the given formatter.

impl From<[u8; 32]> for ContractId

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

Converts to this type from the input type.

impl Hash for ContractId

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

where __H: Hasher,

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 ContractId

fn cmp(&self, other: &ContractId) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for ContractId

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

fn partial_cmp(&self, other: &ContractId) -> 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<__S> Serialize<__S> for ContractId

where __S: Fallible + ?Sized, [u8; 32]: Serialize<__S>,

fn serialize( &self, serializer: &mut __S ) -> Result<<ContractId as Archive>::Resolver, <__S as Fallible>::Error>

Writes the dependencies for the object and returns a resolver that can create the archived type.
