Struct Address 

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

The address of a Solana account.

Some account addresses are ed25519 public keys, with corresponding secret keys that are managed off-chain. Often, though, account addresses do not have corresponding secret keys — as with program derived addresses — or the secret key is not relevant to the operation of a program, and may have even been disposed of. As running Solana programs can not safely create or manage secret keys, the full Keypair is not defined in solana-program but in solana-sdk.

Implementations

impl Address

pub const fn new_from_array(address_array: [u8; 32]) -> Address

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

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

Return a reference to the Address’s byte array.

pub fn is_on_curve(&self) -> bool

Checks whether the given address lies on the Ed25519 curve.

On-curve addresses correspond to valid Ed25519 public keys (and therefore can have associated private keys). Off-curve addresses are typically used for program-derived addresses (PDAs).

Trait Implementations

impl AsMut<[u8]> for Address

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

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

impl AsRef<[u8]> for Address

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

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

impl Clone for Address

fn clone(&self) -> Address

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Address

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

Formats the value using the given formatter.

impl Default for Address

fn default() -> Address

Returns the “default value” for a type.

impl From<&Address> for Address

fn from(value: &Address) -> Address

Converts to this type from the input type.

impl From<[u8; 32]> for Address

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

Converts to this type from the input type.

impl Hash for Address

Custom impl of Hash for Address.

This allows us to skip hashing the length of the address which is always the same anyway.

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 Address

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

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

fn partial_cmp(&self, other: &Address) -> 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 Address

type Error = TryFromSliceError

The type returned in the event of a conversion error.

fn try_from( address: &[u8], ) -> Result<Address, <Address as TryFrom<&[u8]>>::Error>

Performs the conversion.
