[−][src]Struct tentacle_multiaddr::Multiaddr
Representation of a Multiaddr.
Implementations
impl Multiaddr
[src]
pub fn is_empty(&self) -> bool
[src]
Returns true if the multiaddres has no data.
pub fn len(&self) -> usize
[src]
Return the length in bytes of this multiaddress.
pub fn to_vec(&self) -> Vec<u8>
[src]
Return a copy of this Multiaddr
's byte representation.
pub fn push(&mut self, p: Protocol<'_>)
[src]
Adds an already-parsed address component to the end of this multiaddr.
Examples
use tentacle_multiaddr::{Multiaddr, Protocol}; let mut address: Multiaddr = "/ip4/127.0.0.1".parse().unwrap(); address.push(Protocol::TCP(10000)); println!("{}", address); assert_eq!(address, "/ip4/127.0.0.1/tcp/10000".parse().unwrap());
pub fn pop<'a>(&mut self) -> Option<Protocol<'a>>
[src]
Pops the last Protocol
of this multiaddr, or None
if the multiaddr is empty.
use std::net::Ipv4Addr; use tentacle_multiaddr::{Multiaddr, Protocol}; let mut address: Multiaddr = "/ip4/127.0.0.1/tcp/5678".parse().unwrap(); assert_eq!(address.pop().unwrap(), Protocol::TCP(5678)); assert_eq!(address.pop().unwrap(), Protocol::IP4(Ipv4Addr::new(127, 0, 0, 1)));
pub fn iter(&self) -> Iter<'_>ⓘ
[src]
Returns the components of this multiaddress.
use std::net::Ipv4Addr; use tentacle_multiaddr::{Multiaddr, Protocol}; let address: Multiaddr = "/ip4/127.0.0.1/tcp/5678".parse().unwrap(); let components = address.iter().collect::<Vec<_>>(); assert_eq!(components[0], Protocol::IP4(Ipv4Addr::new(127, 0, 0, 1))); assert_eq!(components[1], Protocol::TCP(5678));
pub fn replace<'a, F>(&self, at: usize, by: F) -> Option<Multiaddr> where
F: FnOnce(&Protocol<'_>) -> Option<Protocol<'a>>,
[src]
F: FnOnce(&Protocol<'_>) -> Option<Protocol<'a>>,
Replace a Protocol
at some position in this Multiaddr
.
The parameter at
denotes the index of the protocol at which the function
by
will be applied to the current protocol, returning an optional replacement.
If at
is out of bounds or by
does not yield a replacement value,
None
will be returned. Otherwise a copy of this Multiaddr
with the
updated Protocol
at position at
will be returned.
