Struct AccountMeta 

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

Contains metadata for a single account read or written to by a program during instruction execution.

See [solana_instruction::AccountMeta] for more information.

Fields

pubkey: Pubkey

The account’s public key.

When serialized, encoded to a field named “p” for space efficiency.

is_signer: bool

True if an instruction requires a transaction signature matching this account’s pubkey.

When serialized, encoded to a field named “s” for space efficiency.

is_writable: bool

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

When serialized, encoded to a field named “w” for space efficiency.

Implementations

impl AccountMeta

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

Constructs metatdata for a writable account.

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

Constructs metadata for a readable account.

Trait Implementations

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<(), Error>

Formats the value using the given formatter.

impl Default for AccountMeta

fn default() -> AccountMeta

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for AccountMeta

fn deserialize<__D>( __deserializer: __D, ) -> Result<AccountMeta, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<AccountMeta> for AccountMeta

Available on crate feature solana-instruction-convert-v2 only.

fn from(value: AccountMeta) -> AccountMeta

Converts to this type from the input type.

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 as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for AccountMeta
