Struct Counter

pub struct Counter {
    pub key: Key,
    pub authority: Pubkey,
    pub value: u32,
}

Fields

key: Key

authority: Pubkey

value: u32

Implementations

impl Counter

pub const LEN: usize = 37usize

pub const PREFIX: &'static [u8]

Prefix values used to generate a PDA for this account.

Values are positional and appear in the following order:

0. Counter::PREFIX
1. authority (Pubkey)

pub fn create_pda(authority: Pubkey, bump: u8) -> Result<Pubkey, PubkeyError>

pub fn find_pda(authority: &Pubkey) -> (Pubkey, u8)

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

Trait Implementations

impl BorshDeserialize for Counter

where Key: BorshDeserialize, Pubkey: BorshDeserialize, u32: BorshDeserialize,

fn deserialize_reader<R: Read>(reader: &mut R) -> Result<Self, Error>

fn deserialize(buf: &mut &[u8]) -> Result<Self, Error>

Deserializes this instance from a given slice of bytes. Updates the buffer to point at the remaining bytes.

fn try_from_slice(v: &[u8]) -> Result<Self, Error>

Deserialize this instance from a slice of bytes.

fn try_from_reader<R>(reader: &mut R) -> Result<Self, Error>

where R: Read,

impl BorshSerialize for Counter

where Key: BorshSerialize, Pubkey: BorshSerialize, u32: BorshSerialize,

fn serialize<W: Write>(&self, writer: &mut W) -> Result<(), Error>

fn try_to_vec(&self) -> Result<Vec<u8>, Error>

Serialize this instance into a vector of bytes.

impl Clone for Counter

fn clone(&self) -> Counter

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Counter

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

Formats the value using the given formatter.

impl PartialEq for Counter

fn eq(&self, other: &Counter) -> 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<'a> TryFrom<&AccountInfo<'a>> for Counter

type Error = Error

The type returned in the event of a conversion error.

fn try_from(account_info: &AccountInfo<'a>) -> Result<Self, Self::Error>

Performs the conversion.

impl Eq for Counter

impl StructuralPartialEq for Counter
