fmt::Display helpers for using tracepoint_decode types with format macros like write! and format_args!.

Structs

EventHeaderEnumerator

Helper for getting information from an EventHeader event, e.g. the event name, event attributes, and event fields (field name, type, and value). Enumerate an event as follows:

EventHeaderEnumeratorContext

Context for enumerating the fields of an EventHeader event. Enumerate an event as follows:

EventHeaderEventInfo

Event attributes returned by the event_info() method of EventHeaderEnumerator.

EventHeaderItemInfo

Provides access to the name and value of an EventHeader event item. An item is a field of the event or an element of an array field of the event. This struct is returned by the item_info() method of EventHeaderEnumerator.

PerfByteReader

Helper for working with data that may be in big-endian or little-endian byte order.

PerfConvertOptions

Flags used when formatting a value as a string.

PerfEventAttr

perf_event_attr: Event’s collection parameters.

PerfEventAttrOptions

Bits for PerfEventAttr.Options.

PerfEventAttrReadFormat

perf_event_read_format: bits that can be set in PerfEventAttr.ReadFormat.

PerfEventAttrSampleType

perf_event_sample_format: bits that can be set in PerfEventAttr.SampleType.

PerfEventAttrSize

Values for PerfEventAttr.Size.

PerfEventAttrType

perf_type_id: uint32 value for PerfEventAttr::attr_type.

PerfEventBytes

Represents the header and raw data of a perf event.

PerfEventDesc

Information about the event (shared by all events with the same Id).

PerfEventFormat

Event information parsed from a tracefs “format” file.

PerfEventHeader

perf_event_header: Information at the start of each event.

PerfEventHeaderMisc

Value for PerfEventHeader.Misc.

PerfEventHeaderMiscCpuMode

Values for PerfEventHeaderMisc.CpuMode.

PerfEventHeaderType

perf_event_type: u32 value for PerfEventHeader.Type.

PerfFieldFormat

Stores decoding information about a field, parsed from a tracefs “format” file.

PerfItemMetadata

Provides access to the metadata of a perf event item. An item is a field of the event or an element of an array field of the event.

PerfItemValue

Provides access to the metadata and content of a perf event item. An item is a field of the event or an element of an array field of the event.

PerfMetaOptions

Options for the “meta” suffix generated by EventHeaderEventInfo::json_meta_display, crate::PerfSampleEventInfo::json_meta_display, and crate::PerfNonSampleEventInfo::json_meta_display.

PerfNonSampleEventInfo

Information about a non-sample event, typically returned by reader.get_non_sample_event_info(&bytes).

PerfSampleEventInfo

Information about a sample event, typically returned by reader.get_sample_event_info(&bytes).

PerfSessionInfo

Information about a perf event collection session.

PerfTimeSpec

Semantics equivalent to struct timespec from time.h. Time = 1970 + seconds + nanoseconds.

Enums

EventHeaderEnumeratorError

Values for the last_error() property of EventHeaderEnumerator.

EventHeaderEnumeratorState

Values for the State property of EventHeaderEnumerator.

PerfEventDecodingStyle

Values for the DecodingStyle property of PerfEventFormat.

PerfFieldArray

The type of the array property of PerfFieldFormat. Array-ness of a field.

PerfTextEncoding

Encoding of a string field of an event.
