Struct ContractsStateKey

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

The FuelVM storage double key.

Implementations

impl ContractsStateKey

pub const LEN: usize = 64usize

The length of the underlying array.

pub fn new(first: &ContractId, second: &Bytes32) -> Self

Create a new instance of the double storage key from references.

pub fn from_array(array: [u8; 64]) -> Self

Creates a new instance of double storage key from the array.

pub fn from_slice(slice: &[u8]) -> Result<Self, TryFromSliceError>

Creates a new instance of double storage key from the slice.

pub fn contract_id(&self) -> &ContractId

Returns the reference to the first sub-key.

pub fn state_key(&self) -> &Bytes32

Returns the reference to the second sub-key.

Trait Implementations

impl AsRef<[u8]> for ContractsStateKey

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

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

impl Clone for ContractsStateKey

fn clone(&self) -> ContractsStateKey

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ContractsStateKey

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

Formats the value using the given formatter.

impl Default for ContractsStateKey

fn default() -> Self

Returns the “default value” for a type.

impl From<(&ContractId, &Bytes32)> for ContractsStateKey

fn from(pair: (&ContractId, &Bytes32)) -> Self

Converts to this type from the input type.

impl From<ContractsStateKey> for [u8; 64]

fn from(key: ContractsStateKey) -> [u8; 64]

Converts to this type from the input type.

impl From<ContractsStateKey> for (ContractId, Bytes32)

fn from(key: ContractsStateKey) -> (ContractId, Bytes32)

Converts to this type from the input type.

impl Hash for ContractsStateKey

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 ContractsStateKey

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

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

fn partial_cmp(&self, other: &ContractsStateKey) -> 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 TryFrom<&[u8]> for ContractsStateKey

type Error = TryFromSliceError

The type returned in the event of a conversion error.

fn try_from(slice: &[u8]) -> Result<Self, Self::Error>

Performs the conversion.
