Struct QueryLatestAt

pub struct QueryLatestAt {
    pub index: Option<IndexColumnSelector>,
    pub at: Option<i64>,
    pub fuzzy_descriptors: Vec<String>,
}

A chunk-level latest-at query, aka LatestAtRelevantChunks.

This has the exact same semantics as the query of the same name on our ChunkStore.

Fields

index: Option<IndexColumnSelector>

Which index column should we perform the query on? E.g. log_time.

at: Option<i64>

What index value are we looking for?

fuzzy_descriptors: Vec<String>

Which components are we interested in?

If left unspecified, all existing components are considered of interest.

This will perform a basic fuzzy match on the available columns’ descriptors. The fuzzy logic is a simple case-sensitive contains() query. For example, given a log_tick__SeriesLine:StrokeWidth#width index, all of the following would match: SeriesLine:StrokeWidth#width, StrokeWidth, Stroke, Width, width, SeriesLine, etc.

TODO(cmc): I shall bring that back into a more structured form later. repeated rerun.common.v1alpha1.ComponentDescriptor fuzzy_descriptors = 3;

Implementations

impl QueryLatestAt

pub fn at(&self) -> i64

Returns the value of at, or the default value if at is unset.

Trait Implementations

impl Clone for QueryLatestAt

fn clone(&self) -> QueryLatestAt

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for QueryLatestAt

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

Formats the value using the given formatter.

impl Default for QueryLatestAt

fn default() -> Self

Returns the “default value” for a type.

impl Message for QueryLatestAt

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 Name for QueryLatestAt

const NAME: &'static str = "QueryLatestAt"

Simple name for this Message. This name is the same as it appears in the source .proto file, e.g. FooBar.

const PACKAGE: &'static str = "rerun.manifest_registry.v1alpha1"

Package name this message type is contained in. They are domain-like and delimited by ., e.g. google.protobuf.

fn full_name() -> String

Fully-qualified unique name for this Message. It’s prefixed with the package name and names of any parent messages, e.g. google.rpc.BadRequest.FieldViolation. By default, this is the package name followed by the message name. Fully-qualified names must be unique within a domain of Type URLs.

fn type_url() -> String

Type URL for this Message, which by default is the full name with a leading slash, but may also include a leading domain name, e.g. type.googleapis.com/google.profile.Person. This can be used when serializing into the google.protobuf.Any type.

impl PartialEq for QueryLatestAt

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