Struct ServiceInfo 

pub struct ServiceInfo {
    pub source_timestamp: Option<SystemTime>,
    pub received_timestamp: Option<SystemTime>,
    pub request_id: RequestId,
}

Information about an incoming service request.

Fields

source_timestamp: Option<SystemTime>

Time when the message was published by the publisher.

The rmw layer does not specify the exact point at which the RMW implementation must take the timestamp, but it should be taken consistently at the same point in the process of publishing a message.

received_timestamp: Option<SystemTime>

Time when the message was received by the service node.

The rmw layer does not specify the exact point at which the RMW implementation must take the timestamp, but it should be taken consistently at the same point in the process of receiving a message.

request_id: RequestId

Unique identifier for the request.

Trait Implementations

impl<T, Func, Fut> ClientAsyncCallback<T, ServiceInfo> for Func

impl Clone for ServiceInfo

fn clone(&self) -> ServiceInfo

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ServiceInfo

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

Formats the value using the given formatter.

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<T, F, Func> IntoAsyncServiceCallback<T, ServiceInfo> for Func

where T: Service, Func: FnMut(T::Request, ServiceInfo) -> F + Send + 'static, F: Future<Output = T::Response> + Send + 'static,

fn into_async_service_callback(self) -> AnyServiceCallback<T, ()>

Converts the callback into an enum.

impl<T, Func> IntoNodeServiceCallback<T, ServiceInfo> for Func

where T: Service, Func: Fn(T::Request, ServiceInfo) -> T::Response + Send + Sync + 'static,

fn into_node_service_callback(self) -> AnyServiceCallback<T, ()>

Converts the callback into an enum.

impl<T, Payload, Func> IntoWorkerServiceCallback<T, Payload, ServiceInfo> for Func

where T: Service, Payload: 'static + Send, Func: FnMut(T::Request, ServiceInfo) -> T::Response + Send + 'static,

fn into_worker_service_callback(self) -> AnyServiceCallback<T, Payload>

impl Ord for ServiceInfo

fn cmp(&self, other: &ServiceInfo) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for ServiceInfo

fn eq(&self, other: &ServiceInfo) -> 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 PartialOrd for ServiceInfo

fn partial_cmp(&self, other: &ServiceInfo) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
