Struct Capability 

pub struct Capability {
    pub provider_id: String,
    pub provider_kind: i32,
    pub contract_id: String,
    pub transport: i32,
    pub params: Option<TransportParams>,
    pub description: String,
}

Public view of one declared Capability – what shows up inside CapabilityProvider.capabilities returned by Query. Mirrors the fields of DeclareCapabilityRequest EXCEPT endpoint is OMITTED: endpoint disclosure is gated behind ConnectCapability so Atlas records the consumer->provider edge before any traffic flows. Consumers MUST call ConnectCapability to obtain the dial-able endpoint.

provider_id / provider_kind are duplicated inside each Capability even when it sits inside a CapabilityProvider (where the same info is on the CapabilityProvider itself) – the cost is one extra string + one enum per cap on the wire, and it lets consumers flatten CapabilityProvider.capabilities into a flat Capability list without having to copy the provider info across by hand.

Invariant: params’s oneof variant matches transport – GRPC <-> GrpcParams, ROS2 <-> Ros2Params, MCP <-> McpParams. Atlas enforces this at DeclareCapability time, so a Capability read from Query is guaranteed consistent. Consumers MAY assume this and skip a re-check.

Implementations

impl Capability

pub fn provider_kind(&self) -> Kind

Returns the enum value of provider_kind, or the default if the field is set to an invalid enum value.

pub fn set_provider_kind(&mut self, value: Kind)

Sets provider_kind to the provided enum value.

pub fn transport(&self) -> Transport

Returns the enum value of transport, or the default if the field is set to an invalid enum value.

pub fn set_transport(&mut self, value: Transport)

Sets transport to the provided enum value.

Trait Implementations

impl Clone for Capability

fn clone(&self) -> Capability

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Capability

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

Formats the value using the given formatter.

impl Default for Capability

fn default() -> Self

Returns the “default value” for a type.

impl Hash for Capability

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 Message for Capability

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for Capability

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