Crate re_log_types

Expand description

The different types that make up the rerun log format.

§Feature flags

serde — Enable (de)serialization using serde.

§Mono-components

Some components, mostly transform related ones, are “mono-components”. This means that Rerun makes assumptions that depend on this component only taking on a singular value for all instances of an Entity. Where possible, exposed APIs will force these components to be logged as a singular instance. However, it is an error with undefined behavior to manually use lower-level APIs to log a batched mono-component.

This requirement is especially apparent with transforms: Each entity must have a unique transform chain, e.g. the entity foo/bar/baz is has the transform that is the product of foo.transform * foo/bar.transform * foo/bar/baz.transform.

Re-exports§

pub use self::arrow_msg::ArrowMsg;
pub use self::arrow_msg::ArrowRecordBatchReleaseCallback;
pub use self::path::*;

Modules§

arrow_msg: ArrowMsg is the crate::LogMsg sub-type containing an Arrow payload.
example_components: Example components to be used for tests and docs
external
hash
path: Every logged entity in Rerun is logged to an EntityPath.

Macros§

debug_assert_archetype_has_components: Runtime asserts that an archetype has the given components.
entity_path: Build an EntityPath from parts that are not escaped:
entity_path_vec: Build a Vec<EntityPathPart>:
impl_into_enum

Structs§

ApplicationId: The user-chosen name of the application doing the logging.
BlueprintActivationCommand: Command used for activating a blueprint once it has been fully transmitted.
Duration: A signed duration represented as nanoseconds since unix epoch
EntryId: The id for an entry (i.e. a dataset or a table) in a remote catalog.
Instance: A unique numeric index for each individual instance within a batch.
NonMinI64: An integer that is known not to equal its minimum value.
PythonVersion
ResolvedTimeRange
ResolvedTimeRangeF: Like ResolvedTimeRange, but using TimeReal for improved precision.
SetStoreInfo
StoreId: A unique id per store.
StoreInfo: Information about a recording or blueprint.
TableId: Either the user-chosen name of a table, or an id that is created by the catalog server.
TableMsg: A table, encoded as a dataframe of Arrow record batches.
Time: A date-time represented as nanoseconds since unix epoch
TimeCell: An typed cell of an index, e.g. a point in time on some unknown timeline.
TimeInt: A 64-bit number describing either nanoseconds, sequence numbers or fully static data.
TimePoint: A point in time on any number of Timelines.
TimeReal: Either nanoseconds or sequence numbers.
Timeline: A time frame/space, e.g. log_time or frame_nr, coupled with the type of time it keeps.
TimelineName: The name of a timeline. Often something like "log_time" or "frame_nr".
Timestamp: Encodes a timestamp in nanoseconds since unix epoch.
TryFromIntError: An error type returned when a checked integral type conversion fails (mimics std::num::TryFromIntError)

Enums§

EntryIdOrName: Either an id or a name for an entry.
FileSource
LogMsg: The most general log message sent from the SDK to the server.
PythonVersionParseError
StoreKind: What kind of Store this is.
StoreSource: The source of a recording or blueprint.
TimeType: The type of a TimeInt or crate::Timeline.
TimestampFormat: How to display a crate::Timestamp.

Traits§

VecDequeInsertionExt: Extends VecDeque with extra insertion routines.
VecDequeRemovalExt: Extends VecDeque with extra removal routines.
VecDequeSortingExt: Extends VecDeque with extra sorting routines.

Functions§

build_frame_nr: Build a (Timeline, TimeInt) tuple from frame_nr suitable for inserting in a TimePoint.
build_log_time: Build a (Timeline, TimeInt) tuple from log_time suitable for inserting in a TimePoint.
