Struct AccountMeta 

#[repr(C)]
pub struct AccountMeta {
    pub pubkey: Pubkey,
    pub is_signer: bool,
    pub is_writable: bool,
}

Meta information about an account used to define its role in an instruction. This includes whether the account is a signer and if it’s writable.

Fields

pubkey: Pubkey

is_signer: bool

is_writable: bool

Implementations

impl AccountMeta

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

Creates a new AccountMeta with the given public key as a writable account.

Arguments

• pubkey - The account’s public key
• is_signer - Whether this account is a transaction signer

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

Creates a new read-only AccountMeta with the given public key.

Arguments

• pubkey - The account’s public key
• is_signer - Whether this account is a transaction signer

pub fn serialize(&self) -> [u8; 34]

Serializes the AccountMeta into a fixed-size byte array.

Returns

A 34-byte array containing the serialized account metadata

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

Deserializes an AccountMeta from a byte slice.

Arguments

• data - Byte slice containing serialized account metadata

Returns

A new AccountMeta instance
