Struct enr::Builder

pub struct Builder<K: EnrKey> { /* private fields */ }

The base builder for generating ENR records with arbitrary signing algorithms.

Implementations

impl<K: EnrKey> Builder<K>

pub fn seq(&mut self, seq: u64) -> &mut Self

Modifies the sequence number of the builder.

pub fn add_value<T: Encodable>( &mut self, key: impl AsRef<[u8]>, value: &T ) -> &mut Self

Adds an arbitrary key-value to the ENRBuilder.

pub fn add_value_rlp(&mut self, key: impl AsRef<[u8]>, rlp: Bytes) -> &mut Self

Adds an arbitrary key-value where the value is raw RLP encoded bytes.

pub fn ip(&mut self, ip: IpAddr) -> &mut Self

Adds an ip/ip6 field to the ENRBuilder.

pub fn ip4(&mut self, ip: Ipv4Addr) -> &mut Self

Adds an ip field to the ENRBuilder.

pub fn ip6(&mut self, ip: Ipv6Addr) -> &mut Self

Adds an ip6 field to the ENRBuilder.

pub fn tcp4(&mut self, tcp: u16) -> &mut Self

Adds a tcp field to the ENRBuilder.

pub fn tcp6(&mut self, tcp: u16) -> &mut Self

Adds a tcp6 field to the ENRBuilder.

pub fn udp4(&mut self, udp: u16) -> &mut Self

Adds a udp field to the ENRBuilder.

pub fn udp6(&mut self, udp: u16) -> &mut Self

Adds a udp6 field to the ENRBuilder.

pub fn build(&mut self, key: &K) -> Result<Enr<K>, Error>

Constructs an ENR from the Builder.

Errors

Fails if the identity scheme is not supported, or the record size exceeds MAX_ENR_SIZE.

Trait Implementations

impl<K: EnrKey> Default for Builder<K>

fn default() -> Self

Constructs a minimal Builder for the v4 identity scheme.
