Struct MessageHeader 

pub struct MessageHeader {
    pub num_required_signatures: u8,
    pub num_readonly_signed_accounts: u8,
    pub num_readonly_unsigned_accounts: u8,
}

The message header, identifying signed and read-only account_keys.

Fields

num_required_signatures: u8

The number of signatures required for this message to be considered valid.

num_readonly_signed_accounts: u8

The last num_readonly_signed_accounts of the signed keys are read-only accounts.

num_readonly_unsigned_accounts: u8

The last num_readonly_unsigned_accounts of the unsigned keys are read-only accounts.

Trait Implementations

impl BorshDeserialize for MessageHeader

fn deserialize_reader<__R: Read>(reader: &mut __R) -> Result<Self, Error>

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.

fn try_from_reader<R>(reader: &mut R) -> Result<Self, Error>

where R: Read,

impl BorshSerialize for MessageHeader

fn serialize<__W: Write>(&self, writer: &mut __W) -> Result<(), Error>

impl Clone for MessageHeader

fn clone(&self) -> MessageHeader

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MessageHeader

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MessageHeader

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for MessageHeader

fn eq(&self, other: &MessageHeader) -> 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 MessageHeader

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
