Struct Capabilities 

pub struct Capabilities { /* private fields */ }

Represents all capabilities of a node.

Implementations

impl Capabilities

pub fn new(value: Vec<Capability>) -> Self

Create a new instance from the given vec.

pub const fn supports_eth_at_least(&self, version: &EthVersion) -> bool

Returns true if this peer advertises an eth protocol version that is >= version.

This is not an exact-match check: a peer advertising only eth/71 will return true for any of Eth66..=Eth71, because eth versions are additive — a newer version implies support for the messages of all earlier versions.

Use this to gate requests on a minimum protocol version (e.g. BAL requires eth/71), not to check whether a peer advertises a specific version verbatim. For exact-version checks use the supports_eth_vXX helpers (e.g. Self::supports_eth_v71).

pub fn capabilities(&self) -> &[Capability]

Returns all capabilities.

pub fn into_inner(self) -> Vec<Capability>

Consumes the type and returns the all capabilities.

pub const fn supports_eth(&self) -> bool

Whether the peer supports eth sub-protocol.

pub const fn supports_eth_v66(&self) -> bool

Whether this peer supports eth v66 protocol.

pub const fn supports_eth_v67(&self) -> bool

Whether this peer supports eth v67 protocol.

pub const fn supports_eth_v68(&self) -> bool

Whether this peer supports eth v68 protocol.

pub const fn supports_eth_v69(&self) -> bool

Whether this peer supports eth v69 protocol.

pub const fn supports_eth_v70(&self) -> bool

Whether this peer supports eth v70 protocol.

pub const fn supports_eth_v71(&self) -> bool

Whether this peer supports eth v71 protocol.

Trait Implementations

impl Clone for Capabilities

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Capabilities

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

Formats the value using the given formatter.

impl Decodable for Capabilities

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

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

impl Encodable for Capabilities

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 Eq for Capabilities

impl From<Vec<Capability>> for Capabilities

fn from(value: Vec<Capability>) -> Self

Converts to this type from the input type.

impl PartialEq for Capabilities

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

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.
