Struct ChromeMojoEventInfo

pub struct ChromeMojoEventInfo {
    pub watcher_notify_interface_tag: Option<String>,
    pub ipc_hash: Option<u32>,
    pub mojo_interface_tag: Option<String>,
    pub mojo_interface_method_iid: Option<u64>,
    pub is_reply: Option<bool>,
    pub payload_size: Option<u64>,
    pub data_num_bytes: Option<u64>,
}

Contains information to identify mojo handling events. The trace events in mojo are common for all mojo interfaces and this information is used to identify who is the caller or callee.

Fields

watcher_notify_interface_tag: Option<String>

Contains the interface name or the file name of the creator of a mojo handle watcher, recorded when an event if notified to the watcher. The code that runs within the track event belongs to the interface.

ipc_hash: Option<u32>

The hash of the IPC message that is being handled.

mojo_interface_tag: Option<String>

A static string representing the mojo interface name of the message that is being handled.

mojo_interface_method_iid: Option<u64>

Refers to an interned UnsymbolizedSourceLocation. The UnsymbolizedSourceLocation contains the interface method that’s being handled, represented as a native symbol. The native symbol can be symbolized after the trace is recorded. Not using a symbolized source location for official Chromium builds to reduce binary size - emitting file/function names as strings into the trace requires storing them in the binary, which causes a significant binary size bloat for Chromium.

is_reply: Option<bool>

Indicate whether this is a message or reply.

payload_size: Option<u64>

The payload size of the message being sent through mojo messages.

data_num_bytes: Option<u64>

Represents the size of the message. Includes all headers and user payload.

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

pub fn is_reply(&self) -> bool

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

pub fn payload_size(&self) -> u64

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

pub fn data_num_bytes(&self) -> u64

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

Trait Implementations

impl Clone for ChromeMojoEventInfo

fn clone(&self) -> ChromeMojoEventInfo

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ChromeMojoEventInfo

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

impl Default for ChromeMojoEventInfo

fn default() -> Self

Returns the “default value” for a type.

impl Message for ChromeMojoEventInfo

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>

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,

impl PartialEq for ChromeMojoEventInfo

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