Struct perfetto_consumer_proto::perfetto::protos::TrackEventConfig

pub struct TrackEventConfig {
    pub disabled_categories: Vec<String>,
    pub enabled_categories: Vec<String>,
    pub disabled_tags: Vec<String>,
    pub enabled_tags: Vec<String>,
    pub disable_incremental_timestamps: Option<bool>,
    pub timestamp_unit_multiplier: Option<u64>,
    pub filter_debug_annotations: Option<bool>,
    pub enable_thread_time_sampling: Option<bool>,
    pub filter_dynamic_event_names: Option<bool>,
}

The following fields define the set of enabled trace categories. Each list item is a glob.

To determine if category is enabled, it is checked against the filters in the following order:

1. Exact matches in enabled categories.
2. Exact matches in enabled tags.
3. Exact matches in disabled categories.
4. Exact matches in disabled tags.
5. Pattern matches in enabled categories.
6. Pattern matches in enabled tags.
7. Pattern matches in disabled categories.
8. Pattern matches in disabled tags.

If none of the steps produced a match, the category is enabled by default.

Examples:

• To enable all non-slow/debug categories:

  No configuration needed, happens by default.

• To enable a specific category:

  disabled_categories = [“*”] enabled_categories = [“my_category”]

• To enable only categories with a specific tag:

  disabled_tags = [“*”] enabled_tags = [“my_tag”]

Fields

disabled_categories: Vec<String>

Default: []

enabled_categories: Vec<String>

Default: []

disabled_tags: Vec<String>

Default: [“slow”, “debug”]

enabled_tags: Vec<String>

Default: []

disable_incremental_timestamps: Option<bool>

Default: false (i.e. enabled by default)

timestamp_unit_multiplier: Option<u64>

Allows to specify a custom unit different than the default (ns). Also affects thread timestamps if enable_thread_time_sampling = true. A multiplier of 1000 means that a timestamp = 3 should be interpreted as 3000 ns = 3 us. Default: 1 (if unset, it should be read as 1).

filter_debug_annotations: Option<bool>

Default: false (i.e. debug_annotations is NOT filtered out by default) When true, any debug annotations provided as arguments to the TRACE_EVENT macros are not written into the trace. Typed arguments will still be emitted even if set to true.

enable_thread_time_sampling: Option<bool>

Default : false (i.e. disabled) When true, the SDK samples and emits the current thread time counter value for each event on the current thread’s track. This value represents the total CPU time consumed by that thread since its creation. Note that if a thread is not scheduled by OS for some duration, that time won’t be included in thread_time.

filter_dynamic_event_names: Option<bool>

Default: false (i.e. dynamic event names are NOT filtered out by default) When true, event_names wrapped in perfetto::DynamicString will be filtered out.

impl PartialEq for TrackEventConfig

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