pub struct EthStream<S, N = EthNetworkPrimitives> { /* private fields */ }
Expand description
An EthStream
wraps over any Stream
that yields bytes and makes it
compatible with eth-networking protocol messages, which get RLP encoded/decoded.
Implementations§
Source§impl<S, N> EthStream<S, N>
impl<S, N> EthStream<S, N>
Sourcepub const fn new(version: EthVersion, inner: S) -> Self
pub const fn new(version: EthVersion, inner: S) -> Self
Creates a new unauthed EthStream
from a provided stream. You will need
to manually handshake a peer.
Sourcepub const fn version(&self) -> EthVersion
pub const fn version(&self) -> EthVersion
Returns the eth version.
Sourcepub fn into_inner(self) -> S
pub fn into_inner(self) -> S
Consumes this type and returns the wrapped stream.

impl<S, E, N> EthStream<S, N>
Sourcepub fn start_send_broadcast(
&mut self,
item: EthBroadcastMessage<N>,
) -> Result<(), EthStreamError>
pub fn start_send_broadcast( &mut self, item: EthBroadcastMessage<N>, ) -> Result<(), EthStreamError>
Same as [Sink::start_send
] but accepts a EthBroadcastMessage
instead.
Sourcepub fn start_send_raw(
&mut self,
msg: RawCapabilityMessage,
) -> Result<(), EthStreamError>
pub fn start_send_raw( &mut self, msg: RawCapabilityMessage, ) -> Result<(), EthStreamError>
Sends a raw capability message directly over the stream
