Crate diagnostics_data

Diagnostics data

This library contains the Diagnostics data schema used for inspect and logs . This is the data that the Archive returns on fuchsia.diagnostics.ArchiveAccessor reads.

Macros

• hierarchy
  This macro simplifies creating diagnostics hierarchies, to remove the need of writing multiple nested hierarchies and manually writing all properties.

Structs

• BuilderArgs
  Arguments used to create a new LogsDataBuilder.
• Data
  An instance of diagnostics data with typed metadata and an optional nested payload.
• DiagnosticsHierarchy
  A hierarchy of nodes representing structured data, such as Inspect or structured log data.
• Inspect
  Inspect carries snapshots of data trees hosted by components.
• InspectDataBuilder
• InspectError
  Possible error that can come in a DiagnosticsData object where the data source is DataSource::Inspect..
• InspectMetadata
  The metadata contained in a DiagnosticsData object where the data source is DataSource::Inspect.
• LogTextDisplayOptions
  Display options for unstructured logs.
• LogTextPresenter
  Used to control stringification options of Data
• Logs
  Logs carry streams of structured events from components.
• LogsDataBuilder
  Internal state of the LogsDataBuilder impl External customers should not directly access these fields.
• LogsMetadata
  The metadata contained in a DiagnosticsData object where the data source is DataSource::Logs.

Enums

• DataSource
  The source of diagnostics data
• Error
  Errors that can happen in this library.
• ExtendedMoniker
  One of:
• InspectHandleName
  The possible name for a handle to inspect data. It could be a filename (being deprecated) or a name published using fuchsia.inspect.InspectSink.
• LogError
  Possible errors that can come in a DiagnosticsData object where the data source is DataSource::Logs.
• LogTextColor
  Configuration for the color of a log line that is displayed in tools using LogTextPresenter.
• LogTimeDisplayFormat
  Configuration for how to display the timestamp associated to a log line.
• LogsField
  An enum containing well known argument names passed through logs, as well as an Other variant for any other argument names.
• Property
  A named property. Each of the fields consists of (name, value).
• Severity
  Severities a log message can have, often called the log’s “level”.
• Timezone
  Options for the timezone associated to the timestamp of a log line.

Constants

• DROPPED_LABEL
  The label for the number of dropped logs in the log metadata.
• FILE_PATH_LABEL
  The label for the file associated with a log line.
• LINE_NUMBER_LABEL
  The label for the line number in the file associated with a log line.
• MESSAGE_LABEL
  The label for the message in the log payload.
• MESSAGE_LABEL_STRUCTURED
  The label for the contents of a message in the log payload.
• PID_LABEL
  The label for the process koid in the log metadata.
• TAG_LABEL
  The label for a tag in the log metadata.
• TID_LABEL
  The label for the thread koid in the log metadata.

Traits

• DiagnosticsData
  A trait implemented by marker types which denote “kinds” of diagnostics data.
• Metadata
• MetadataError

Functions

• deserialize_timestamp
• serialize_timestamp

Type Aliases

• InspectData
  A diagnostics data object containing inspect data.
• LogsData
  A diagnostics data object containing logs data.
• LogsHierarchy
  A diagnostics data payload containing logs data.
• LogsProperty
  A diagnostics hierarchy property keyed by LogsField.
• Timestamp
