Struct NodeRecord

pub struct NodeRecord {
    pub address: IpAddr,
    pub udp_port: u16,
    pub tcp_port: u16,
    pub id: PeerId,
}

Represents a ENR in discovery.

Note: this is only an excerpt of the NodeRecord data structure.

Fields

address: IpAddr

The Address of a node.

udp_port: u16

UDP discovery port.

tcp_port: u16

TCP port of the port that accepts connections.

id: PeerId

Public key of the discovery service

Implementations

impl NodeRecord

pub fn from_secret_key(addr: SocketAddr, sk: &SecretKey) -> Self

Available on crate feature secp256k1 only.

Derive the NodeRecord from the secret key and addr.

Note: this will set both the TCP and UDP ports to the port of the addr.

pub fn convert_ipv4_mapped(&mut self) -> bool

Converts the address into an Ipv4Addr if the address is a mapped Ipv6Addr.

Returns true if the address was converted.

See also std::net::Ipv6Addr::to_ipv4_mapped

pub fn into_ipv4_mapped(self) -> Self

Same as Self::convert_ipv4_mapped but consumes the type

pub const fn with_tcp_port(self, port: u16) -> Self

Sets the tcp port

pub const fn with_udp_port(self, port: u16) -> Self

Sets the udp port

pub const fn new(addr: SocketAddr, id: PeerId) -> Self

Creates a new record from a socket addr and peer id.

pub fn new_with_ports( ip_addr: IpAddr, tcp_port: u16, udp_port: Option<u16>, id: PeerId, ) -> Self

Creates a new record from an ip address and ports.

pub const fn tcp_addr(&self) -> SocketAddr

The TCP socket address of this node

pub const fn udp_addr(&self) -> SocketAddr

The UDP socket address of this node

Trait Implementations

impl Clone for NodeRecord

fn clone(&self) -> NodeRecord

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NodeRecord

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

Formats the value using the given formatter.

impl Decodable for NodeRecord

fn decode(b: &mut &[u8]) -> Result<Self>

Decodes the blob into the appropriate type. buf must be advanced past the decoded object.

impl<'de> Deserialize<'de> for NodeRecord

where Self: FromStr, <Self as FromStr>::Err: Display,

fn deserialize<__D>(deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for NodeRecord

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

Formats the value using the given formatter.

impl Encodable for NodeRecord

fn length(&self) -> usize

Returns the length of the encoding of this type in bytes.

fn encode(&self, out: &mut dyn BufMut)

Encodes the type into the out buffer.

impl From<NodeRecord> for AnyNode

fn from(value: NodeRecord) -> Self

Converts to this type from the input type.

impl From<NodeRecord> for TrustedPeer

fn from(record: NodeRecord) -> Self

Converts to this type from the input type.

impl FromStr for NodeRecord

type Err = NodeRecordParseError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for NodeRecord

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for NodeRecord

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

impl Serialize for NodeRecord

where Self: Display,

fn serialize<__S>(&self, serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

fn try_from(enr: &Enr<SecretKey>) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<Enr<SecretKey>> for NodeRecord

Available on crate feature secp256k1 only.

type Error = NodeRecordParseError

The type returned in the event of a conversion error.

fn try_from(enr: Enr<SecretKey>) -> Result<Self, Self::Error>

Performs the conversion.

impl Copy for NodeRecord

impl Eq for NodeRecord

impl StructuralPartialEq for NodeRecord

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
