Struct ProcessSnapshot

pub struct ProcessSnapshot {
    pub pid: Option<i32>,
    pub allocator_dumps: Vec<MemoryNode>,
    pub memory_edges: Vec<MemoryEdge>,
}

Memory snapshot of a process. The snapshot contains memory data that is from 2 different sources, namely system stats and instrumentation stats. The system memory usage stats come from the OS based on standard API available in the platform to query memory usage. The instrumentation stats are added by instrumenting specific piece of code which tracks memory allocations and deallocations made by a small sub-system within the application. The system stats of the global memory snapshot are recorded as part of ProcessStats and SmapsPacket fields in trace packet with the same timestamp.

Fields

pid: Option<i32>

Process ID of the process

allocator_dumps: Vec<MemoryNode>

memory_edges: Vec<MemoryEdge>

Implementations

impl ProcessSnapshot

pub fn pid(&self) -> i32

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

Trait Implementations

impl Clone for ProcessSnapshot

fn clone(&self) -> ProcessSnapshot

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ProcessSnapshot

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

Formats the value using the given formatter.

impl Default for ProcessSnapshot

fn default() -> Self

Returns the “default value” for a type.

impl Message for ProcessSnapshot

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 ProcessSnapshot

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