Implementations

impl ApplicationProtocol

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

pub fn try_as_str(&self) -> Option<&str>

impl ApplicationProtocol

pub fn encode_wire_format( &self, writer: &mut impl Write, ) -> Result<usize, Error>

Available on crate feature std only.

Encode one RFC 7301 length-prefixed protocol name.

Errors

Returns std::io::ErrorKind::InvalidData when the identifier is empty or exceeds 255 octets, and forwards writer errors.

pub fn decode_wire_format( reader: &mut impl Read, ) -> Result<ApplicationProtocol, Error>

Available on crate feature std only.

Decode one RFC 7301 length-prefixed protocol name.

Errors

Returns std::io::ErrorKind::InvalidData for an empty identifier and forwards reader errors.

pub fn encode_alpns(alpns: &[ApplicationProtocol]) -> Result<Bytes, Error>

Available on crate feature std only.

Encode consecutive RFC 7301 length-prefixed protocol names.

An empty slice produces an empty buffer, allowing callers to represent an omitted ALPN offer.

Errors

Returns an error when any protocol name is invalid or writing fails.
