Implementations

impl ContractAddress

pub const ONE: ContractAddress

The contract at 0x1 is special. It was never deployed and therefore has no class hash. It does however receive storage changes.

It is used by starknet to store values for smart contracts to access using syscalls. For example the block hash.

pub const TWO: ContractAddress

The contract at 0x2 was introduced in Starknet version 0.13.4. It is used for stateful compression:

• storage key 0 points to the global counter, which is the base for index values in the next block,
• other storage k-v pairs store the mapping of key to index,
• the global counter starts at value 0x80 in the first block from 0.13.4,
• keys of value lower than 0x80 are not indexed.

pub const SYSTEM: [ContractAddress; 2]

Useful for iteration over the system contracts

Trait Implementations

impl Clone for ContractAddress

fn clone(&self) -> ContractAddress

Returns a duplicate of the value.

fn default() -> ContractAddress

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ContractAddress

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

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ContractAddress

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

Formats the value using the given formatter.

impl Dummy<Faker> for ContractAddress

fn dummy_with_rng<R: Rng + ?Sized>(_: &Faker, rng: &mut R) -> Self

Generate a dummy value for a given type using a random number generator.

fn dummy(config: &T) -> Self

impl From<ContractAddress> for Vec<u8>

fn from(value: ContractAddress) -> Self

Converts to this type from the input type.

impl Hash for ContractAddress

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,

impl Ord for ContractAddress

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

impl PartialEq for ContractAddress

fn eq(&self, other: &ContractAddress) -> 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.
