Protocol describes all possible multiaddress protocols.

For Unix, Ws and Wss we use &str instead of Path to allow cross-platform usage of Protocol since encoding Paths to bytes is platform-specific. This means that the actual validation of paths needs to happen separately.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Implementations

impl<'a> Protocol<'a>

pub fn from_str_parts<I>(iter: I) -> Result<Protocol<'a>, Error>

where I: Iterator<Item = &'a str>,

Parse a protocol value from the given iterator of string slices.

The parsing only consumes the minimum amount of string slices necessary to produce a well-formed protocol. The same iterator can thus be used to parse a sequence of protocols in succession. It is up to client code to check that iteration has finished whenever appropriate.

pub fn from_bytes(input: &'a [u8]) -> Result<(Protocol<'a>, &'a [u8]), Error>

Parse a single Protocol value from its byte slice representation, returning the protocol as well as the remaining byte slice.

pub fn write_bytes<W>(&self, w: &mut W) -> Result<(), Error>

where W: Write,

Encode this protocol by writing its binary representation into the given Write impl.

pub fn acquire<'b>(self) -> Protocol<'b>

Turn this Protocol into one that owns its data, thus being valid for any lifetime.

pub fn tag(&self) -> &'static str

Trait Implementations

impl<'a> Clone for Protocol<'a>

fn clone(&self) -> Protocol<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Protocol<'a>

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

Formats the value using the given formatter.

impl<'a> Display for Protocol<'a>

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

Formats the value using the given formatter.

impl<'a> From<IpAddr> for Protocol<'a>

fn from(addr: IpAddr) -> Protocol<'a>

Converts to this type from the input type.

impl<'a> From<Ipv4Addr> for Protocol<'a>

fn from(addr: Ipv4Addr) -> Protocol<'a>

Converts to this type from the input type.

impl<'a> From<Ipv6Addr> for Protocol<'a>

fn from(addr: Ipv6Addr) -> Protocol<'a>

Converts to this type from the input type.

impl<'a> From<Protocol<'a>> for Multiaddr

fn from(p: Protocol<'a>) -> Multiaddr

Converts to this type from the input type.

impl<'a> FromIterator<Protocol<'a>> for Multiaddr

fn from_iter<T>(iter: T) -> Multiaddr

where T: IntoIterator<Item = Protocol<'a>>,

Creates a value from an iterator.

impl<'a> PartialEq for Protocol<'a>

fn eq(&self, other: &Protocol<'a>) -> 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.
