Struct GenericEventDescriptor 

pub struct GenericEventDescriptor {
    pub field_id: Option<i32>,
    pub group_name: Option<String>,
    pub event_descriptor: Option<Vec<u8>>,
}

Describes the serialised |FtraceEvent| protos for events not known at compile time, when using the |denser_generic_event_encoding| option. Addded in: perfetto v50.

Fields

field_id: Option<i32>

submessage id within FtraceEvent described by |event_descriptor|.

group_name: Option<String>

optional: the event’s group, e.g. “sched” for “sched/sched_switch”. The event name itself is in |event_descriptor.name|.

event_descriptor: Option<Vec<u8>>

serialised DescriptorProto.

Implementations

impl GenericEventDescriptor

pub fn field_id(&self) -> i32

Returns the value of field_id, or the default value if field_id is unset.

pub fn event_descriptor(&self) -> &[u8]

Returns the value of event_descriptor, or the default value if event_descriptor is unset.

pub fn group_name(&self) -> &str

Returns the value of group_name, or the default value if group_name is unset.

Trait Implementations

impl Clone for GenericEventDescriptor

fn clone(&self) -> GenericEventDescriptor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GenericEventDescriptor

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

Formats the value using the given formatter.

impl Default for GenericEventDescriptor

fn default() -> Self

Returns the “default value” for a type.

impl Hash for GenericEventDescriptor

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Message for GenericEventDescriptor

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

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

where 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(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

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

where Self: Default,

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

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

where Self: Sized,

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

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

where Self: Sized,

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

impl PartialEq for GenericEventDescriptor

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