Trait Implementations

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 Borrow<[u8; 32]> for ContractId

fn borrow(&self) -> &[u8; 32]

Immutably borrows from an owned value.

impl BorrowMut<[u8; 32]> for ContractId

fn borrow_mut(&mut self) -> &mut [u8; 32]

Mutably borrows from an owned 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

Formats the value using the given formatter.

impl Default for ContractId

fn default() -> ContractId

Returns the “default value” for a type.

impl Deref for ContractId

type Target = [u8; 32]

The resulting type after dereferencing.

fn deref(&self) -> &[u8; 32]

Dereferences the value.

impl DerefMut for ContractId

fn deref_mut(&mut self) -> &mut [u8; 32]

Mutably dereferences the value.

impl Deserialize for ContractId

fn decode_static<I: Input + ?Sized>(buffer: &mut I) -> Result<Self, Error>

Decodes static part of Self from the buffer.

fn decode_dynamic<I: Input + ?Sized>( &mut self, buffer: &mut I, ) -> Result<(), Error>

Decodes dynamic part of the information from the buffer to fill Self. The default implementation does nothing. Dynamically-sized contains should override this.

fn decode<I: Input + ?Sized>(buffer: &mut I) -> Result<Self, Error>

Decodes Self from the buffer.

fn from_bytes(buffer: &[u8]) -> Result<Self, Error>

Helper method for deserializing Self from bytes.

impl Display for ContractId

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

Formats the value using the given formatter.

impl From<[u8; 32]> for ContractId

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

Converts to this type from the input type.

impl From<ContractId> for [u8; 32]

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

Converts to this type from the input type.

impl FromStr for ContractId

type Err = &'static str

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for ContractId

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 LowerHex for ContractId

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

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,

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.

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.
