Implementations

impl HelloMessage

pub fn new( endpoint_url: &str, send_buffer_size: usize, receive_buffer_size: usize, max_message_size: usize, max_chunk_count: usize, ) -> HelloMessage

Creates a HEL message

pub fn is_endpoint_url_valid(&self, endpoints: &[EndpointDescription]) -> bool

pub fn is_endpoint_valid_length(&self) -> bool

pub fn matches_endpoint(&self, endpoints: &[EndpointDescription]) -> bool

pub fn is_valid_buffer_sizes(&self) -> bool

Trait Implementations

impl BinaryEncoder<HelloMessage> for HelloMessage

fn byte_len(&self) -> usize

Returns the exact byte length of the structure as it would be if encode were called. This may be called prior to writing to ensure the correct amount of space is available.

fn encode<S>(&self, stream: &mut S) -> Result<usize, StatusCode>

where S: Write,

Encodes the instance to the write stream.

fn decode<S>( stream: &mut S, decoding_options: &DecodingOptions, ) -> Result<HelloMessage, StatusCode>

where S: Read,

Decodes an instance from the read stream. The decoding options contains restrictions set by the server / client on the length of strings, arrays etc. If these limits are exceeded the implementation should return with a BadDecodingError as soon as possible.

fn encode_to_vec(&self) -> Vec<u8>

impl Clone for HelloMessage

fn clone(&self) -> HelloMessage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HelloMessage

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

Formats the value using the given formatter.

impl PartialEq for HelloMessage

fn eq(&self, other: &HelloMessage) -> 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.
