Struct exonum::messages::MessageBuffer

pub struct MessageBuffer { /* fields omitted */ }

A raw message represented by the bytes buffer.

Methods

impl MessageBuffer

pub fn from_vec(raw: Vec<u8>) -> Self

Creates MessageBuffer instance from the bytes vector.

Example

use exonum::messages::MessageBuffer;

let message_buffer = MessageBuffer::from_vec(vec![1, 2, 3]);
assert!(!message_buffer.is_empty());

pub 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());

pub 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());

pub fn version(&self) -> u8

Returns the protocol version.

pub fn service_id(&self) -> u16

Returns id of the service.

pub fn message_type(&self) -> u16

Returns type of the message.

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

Returns message body without signature.

pub fn signature(&self) -> &Signature

Returns signature of the message.

pub 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.

pub 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.
