Struct AccountMeta 

pub struct AccountMeta {
    pub pubkey: PublicKey,
    pub is_signer: bool,
    pub is_writable: bool,
}

Fields

pubkey: PublicKey

An account’s public key.

is_signer: bool

True if an Instruction requires a Transaction signature matching pubkey.

is_writable: bool

True if the account data or metadata may be mutated during program execution.

Implementations

impl AccountMeta

pub fn new(pubkey: PublicKey, is_signer: bool) -> Self

pub fn new_readonly(pubkey: PublicKey, is_signer: bool) -> Self

Trait Implementations

impl BorshDeserialize for AccountMeta

where PublicKey: BorshDeserialize, bool: BorshDeserialize,

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.

impl BorshSerialize for AccountMeta

where PublicKey: BorshSerialize, bool: 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 AccountMeta

fn clone(&self) -> AccountMeta

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AccountMeta

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

Formats the value using the given formatter.

impl Hash for AccountMeta

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 PartialEq for AccountMeta

fn eq(&self, other: &AccountMeta) -> 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 Serialize for AccountMeta

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for AccountMeta
