Struct DataSource

pub struct DataSource {
    pub config: Option<DataSourceConfig>,
    pub producer_name_filter: Vec<String>,
    pub producer_name_regex_filter: Vec<String>,
    pub machine_name_filter: Vec<String>,
}

Fields

config: Option<DataSourceConfig>

Filters and data-source specific config. It contains also the unique name of the data source, the one passed in the DataSourceDescriptor when they register on the service.

producer_name_filter: Vec<String>

Optional. If multiple producers (~processes) expose the same data source and either |producer_name_filter| or |producer_name_regex_filter| is set, the data source is enabled only for producers whose names match any of the filters. |producer_name_filter| has to be an exact match, while |producer_name_regex_filter| is a regular expression. This allows to enable a data source only for specific processes. The “repeated” fields have OR semantics: specifying a filter [“foo”, “bar”] will enable data sources on both “foo” and “bar” (if they exist).

producer_name_regex_filter: Vec<String>

machine_name_filter: Vec<String>

Filter by machine names. The name of a machine is determined by the PERFETTO_MACHINE_NAME env variable. In Android systems, if the env variable is not set then the persist.traced_relay.machine_name system property is used. If the sysprop isn’t set or not in an Android system, then the machine name by default is set to the utsname sysname (e.g. Linux), which can be obtained via the ‘uname -s’ command. As a convenience, one can use “host” to refer to the host machine, which is the machine running traced.

Trait Implementations

impl Clone for DataSource

fn clone(&self) -> DataSource

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DataSource

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

Formats the value using the given formatter.

impl Default for DataSource

fn default() -> Self

Returns the “default value” for a type.

impl Message for DataSource

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<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, 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<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, 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<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for DataSource

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

Tests for self and other values to be equal, and is used by ==.

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

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