Struct ContractId 

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

Type used to identify a contract

Implementations

impl ContractId

pub const fn reserved(id: u8) -> ContractId

Return a reserved contract id for host fn modules

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

Returns the contract id as a byte slice

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

Returns the contract id as a mutable slice

pub const fn from_raw(b: [u8; 32]) -> ContractId

Returns a ContractId from an array of 32 bytes

Trait Implementations

impl Canon for ContractId

fn encode(&self, sink: &mut Sink<'_>)

Write the encoded value as bytes to a Sink

fn decode(source: &mut Source<'_>) -> Result<ContractId, CanonError>

Return the decoded value from bytes in a Source

fn encoded_len(&self) -> usize

Returns the number of bytes needed to encode this value

impl Clone for ContractId

fn clone(&self) -> ContractId

Returns a duplicate 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 Default for ContractId

fn default() -> ContractId

Returns the “default value” for a type.

impl Display for ContractId

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

Formats the value using the given formatter.

impl<B> From<B> for ContractId

where B: AsRef<[u8]>,

fn from(b: B) -> 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 LowerHex for ContractId

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

Formats the value using the given formatter.

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,

Restrict a value to a certain interval.

impl PartialEq for ContractId

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

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 UpperHex for ContractId

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

Formats the value using the given formatter.
