Fields

view_contents: Option<ViewContents>

The subset of the database that the query will run on: a set of EntityPath(s) and their associated Component(s)

include_semantically_empty_columns: bool

Whether the view_contents should ignore semantically empty columns A semantically empty column is a column that either contains no data at all, or where all values are either nulls or empty arrays ([]).

include_indicator_columns: bool

Whether the view_contents should ignore columns corresponding to indicator components Indicator components are marker components, generally automatically inserted by Rerun, that helps keep track of the original context in which a piece of data was logged/sent.

include_tombstone_columns: bool

Whether the view_contents should ignore columns corresponding to Clear-related components

filtered_index: Option<IndexColumnSelector>

The index used to filter out rows from the view contents. Only rows where at least 1 column contains non-null data at that index will be kept in the final dataset. If left unspecified, the results will only contain static data.

filtered_index_range: Option<IndexRange>

The range of index values used to filter out rows from the view contents Only rows where at least 1 of the view-contents contains non-null data within that range will be kept in the final dataset. This has no effect if filtered_index isn’t set. This has no effect if using_index_values is set.

filtered_index_values: Option<IndexValues>

The specific index values used to filter out rows from the view contents. Only rows where at least 1 column contains non-null data at these specific values will be kept in the final dataset. This has no effect if filtered_index isn’t set. This has no effect if using_index_values is set.

using_index_values: Option<IndexValues>

The specific index values used to sample rows from the view contents. The final dataset will contain one row per sampled index value, regardless of whether data existed for that index value in the view contents. The semantics of the query are consistent with all other settings: the results will be sorted on the filtered_index, and only contain unique index values.

This has no effect if filtered_index isn’t set. If set, this overrides both filtered_index_range and filtered_index_values.

filtered_is_not_null: Option<ComponentColumnSelector>

The component column used to filter out rows from the view contents. Only rows where this column contains non-null data be kept in the final dataset.

column_selection: Option<ColumnSelection>

/ The specific columns to sample from the final view contents. / The order of the samples will be respected in the final result. / / If unspecified, it means - everything.

sparse_fill_strategy: i32

Specifies how null values should be filled in the returned dataframe.

Implementations

impl Query

pub fn sparse_fill_strategy(&self) -> SparseFillStrategy

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

pub fn set_sparse_fill_strategy(&mut self, value: SparseFillStrategy)

Sets sparse_fill_strategy to the provided enum value.

Trait Implementations

impl Clone for Query

fn clone(&self) -> Query

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Query

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

Formats the value using the given formatter.

impl Default for Query

fn default() -> Self

Returns the “default value” for a type.

impl From<QueryExpression> for Query

fn from(value: QueryExpression) -> Self

Converts to this type from the input type.

impl Message for Query

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 Query

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<Query> for QueryExpression

type Error = TypeConversionError

The type returned in the event of a conversion error.

fn try_from(value: Query) -> Result<Self, Self::Error>

Performs the conversion.

impl StructuralPartialEq for Query
