Struct Update

pub struct Update {
    pub now: Option<Timestamp>,
    pub task_update: Option<TaskUpdate>,
    pub resource_update: Option<ResourceUpdate>,
    pub async_op_update: Option<AsyncOpUpdate>,
    pub new_metadata: Option<RegisterMetadata>,
}

Update carries all information regarding tasks, resources, async operations and resource operations in one message. There are a couple of reasons to combine all of these into a single message:

• we can use one single timestamp for all the data
• we can have all the new_metadata in one place
• things such as async ops and resource ops do not make sense on their own as they have relations to tasks and resources

Fields

now: Option<Timestamp>

The system time when this update was recorded.

This is the timestamp any durations in the included Stats were calculated relative to.

task_update: Option<TaskUpdate>

Task state update.

resource_update: Option<ResourceUpdate>

Resource state update.

async_op_update: Option<AsyncOpUpdate>

Async operations state update

new_metadata: Option<RegisterMetadata>

Any new span metadata that was registered since the last update.

Trait Implementations

impl Clone for Update

fn clone(&self) -> Update

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Update

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

Formats the value using the given formatter.

impl Default for Update

fn default() -> Self

Returns the “default value” for a type.

impl Message for Update

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 Update

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