pub struct AccountMetaData {
    pub pubkey: Pubkey,
    pub is_signer: bool,
    pub is_writable: bool,
}
Expand description

Account metadata needed to execute an instruction on Solana.

Fields§

§pubkey: Pubkey

An account’s public key

§is_signer: bool

True if an Instruction requires a Transaction signature matching pubkey.

§is_writable: bool

True if the pubkey can be loaded as a read-write account.

Implementations§

source§

impl AccountMetaData

source

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

Construct metadata for a writable account.

source

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

Construct metadata for a read-only account.

Trait Implementations§

source§

impl BorshDeserialize for AccountMetaDatawhere
    Pubkey: BorshDeserialize,
    bool: BorshDeserialize,

source§

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.
source§

impl BorshSchema for AccountMetaDatawhere
    Pubkey: BorshSchema,
    bool: BorshSchema,

source§

fn declaration() -> Declaration

Get the name of the type without brackets.
source§

fn add_definitions_recursively(
    definitions: &mut HashMap<Declaration, Definition>
)

Recursively, using DFS, add type definitions required for this type. For primitive types this is an empty map. Type definition explains how to serialize/deserialize a type.
§

fn add_definition(
    declaration: String,
    definition: Definition,
    definitions: &mut HashMap<String, Definition, RandomState>
)

Helper method to add a single type definition to the map.

impl PartialEq<AccountMetaData> for AccountMetaData

source§

fn eq(&self, other: &AccountMetaData) -> bool

This method tests for self and other values to be equal, and is used by ==.
1.0.0 · source§

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
