Struct exonum::messages::RawMessage

pub struct RawMessage(_);

Thread-safe reference-counting pointer to the MessageBuffer.

Methods

impl RawMessage

fn new(buffer: MessageBuffer) -> Self

Creates a new RawMessage instance with the given MessageBuffer.

Methods from Deref<Target = MessageBuffer>

fn len(&self) -> usize

Returns the length of the message in bytes.

Example

use exonum::messages::MessageBuffer;

let data = vec![1, 2, 3];
let message_buffer = MessageBuffer::from_vec(data.clone());
assert_eq!(data.len(), message_buffer.len());

fn is_empty(&self) -> bool

Returns true if the MessageBuffer contains no bytes.

# Example

use exonum::messages::MessageBuffer;
;
 let message_buffer = MessageBuffer::from_vec(vec![]);
 assert!(message_buffer.is_empty());

fn network_id(&self) -> u8

Returns network id.

fn version(&self) -> u8

Returns the protocol version.

fn service_id(&self) -> u16

Returns id of the service.

fn message_type(&self) -> u16

Returns type of the message.

fn body(&self) -> &[u8]

Returns message body without signature.

fn signature(&self) -> &Signature

Returns signature of the message.

fn check<'a, F: Field<'a>>(
    &'a self,
    from: CheckedOffset,
    to: CheckedOffset,
    latest_segment: CheckedOffset
) -> StreamStructResult

Checks that Field can be safely got with specified from and to offsets.

unsafe fn read<'a, F: Field<'a>>(&'a self, from: Offset, to: Offset) -> F

Returns Field specified by from and to offsets. Should not be used directly.
