Struct AccountMetaData 

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

AccountMetaData

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.

Trait Implementations

impl BorshDeserialize for AccountMetaData

where Pubkey: 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 AccountMetaData

where Pubkey: 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 BorshSchema for AccountMetaData

where Pubkey: BorshSchema, bool: BorshSchema,

fn declaration() -> Declaration

Get the name of the type without brackets.

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>, )

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

fn schema_container() -> BorshSchemaContainer

impl Clone for AccountMetaData

fn clone(&self) -> AccountMetaData

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AccountMetaData

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

Formats the value using the given formatter.

impl Hash for AccountMetaData

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 AccountMetaData

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