Struct SetPeerIdentity

pub struct SetPeerIdentity {
    pub pid: Option<i32>,
    pub uid: Option<i32>,
    pub machine_id_hint: Option<String>,
    pub machine_name: Option<String>,
}

Client (relay service) -> Host. This is generated by the relay service to fill the producer identity in the guest. This message is sent to the host service before any IPCFrame is from a local producer is relayed. This is accepted only on AF_VSOCK and AF_INET sockets, where we cannot validate the endpoont of the connection. for AF_UNIX sockets, this is ignored and traced uses instead the SO_PEERCRED.

Fields

pid: Option<i32>

The UID and PID of the producer process.

uid: Option<i32>

machine_id_hint: Option<String>

The hint for the tracing service to infer the machine ID. This field should satisfy the requriement that different machines should have different values. In practice, this filed contains the Linux kernel boot_id, or a hash of kernel bootup timestamp and uname(2) if boot_id isn’t available.

machine_name: Option<String>

Human-readable name associated to the producer’s machine. Provides the tracing service a new dimension to filter data sources on. Given the perfetto machine name is provided by users, there is no expectation of uniqueness across machines in a tracing session.

Implementations

impl SetPeerIdentity

pub fn pid(&self) -> i32

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

pub fn uid(&self) -> i32

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

pub fn machine_id_hint(&self) -> &str

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

pub fn machine_name(&self) -> &str

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

Trait Implementations

impl Clone for SetPeerIdentity

fn clone(&self) -> SetPeerIdentity

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SetPeerIdentity

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

Formats the value using the given formatter.

impl Default for SetPeerIdentity

fn default() -> Self

Returns the “default value” for a type.

impl Message for SetPeerIdentity

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 SetPeerIdentity

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