Struct TypedAddress 

pub struct TypedAddress<T> { /* private fields */ }

A 32-byte public key tagged with a phantom layout type.

Zero-cost: #[repr(transparent)] over [u8; 32], align 1. The type parameter T exists only at compile time for type safety – it has no runtime representation.

Implementations

impl<T> TypedAddress<T>

pub const fn new(bytes: [u8; 32]) -> TypedAddress<T>

Create a typed address from raw bytes.

pub fn from_slice(slice: &[u8; 32]) -> TypedAddress<T>

Create from a byte slice reference (copies 32 bytes).

pub fn from_account(account: &AccountView) -> TypedAddress<T>

Create from an AccountView’s address.

pub const fn zeroed() -> TypedAddress<T>

The zero address (all bytes 0).

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

Raw 32-byte key.

pub fn eq_bytes(&self, other: &[u8; 32]) -> bool

Check if this address equals a raw 32-byte key.

pub fn eq_account(&self, account: &AccountView) -> bool

Check if this address matches an AccountView’s address.

pub fn require_eq_account( &self, account: &AccountView, ) -> Result<(), ProgramError>

Verify this address matches the given account, returning an error if not.

pub fn is_zero(&self) -> bool

Check if this is the zero address.

pub const fn cast<U>(self) -> TypedAddress<U>

Cast this typed address to a different type.

Use sparingly – this exists for interop with legacy/untyped code.

pub const fn untyped(self) -> UntypedAddress

Erase the type tag, returning an untyped address.

Trait Implementations

impl<T> AsRef<[u8]> for TypedAddress<T>

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

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

impl<T> AsRef<[u8; 32]> for TypedAddress<T>

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

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

impl<T> Clone for TypedAddress<T>

fn clone(&self) -> TypedAddress<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T> Debug for TypedAddress<T>

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

Formats the value using the given formatter.

impl<T> FixedLayout for TypedAddress<T>

const SIZE: usize = 32

Total byte size on the wire (including any header if applicable).

impl<T> From<[u8; 32]> for TypedAddress<T>

fn from(bytes: [u8; 32]) -> TypedAddress<T>

Converts to this type from the input type.

impl<T> PartialEq<[u8; 32]> for TypedAddress<T>

fn eq(&self, other: &[u8; 32]) -> 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<T> PartialEq for TypedAddress<T>

fn eq(&self, other: &TypedAddress<T>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool
