Struct MemoryNode 

pub struct MemoryNode {
    pub id: Option<u64>,
    pub absolute_name: Option<String>,
    pub weak: Option<bool>,
    pub size_bytes: Option<u64>,
    pub entries: Vec<MemoryNodeEntry>,
}

A single node in the memory graph.

Fields

id: Option<u64>

Unique ID of the node across all processes involved in the global memory dump. The ID is only unique within this particular global dump identified by GlobalMemoryDumpPacket.global_dump_id.

absolute_name: Option<String>

Absolute name is a unique name for the memory node within the process with ProcessMemoryDump.pid. The name can contain multiple parts separated by ‘/’, which traces the edges of the node from the root node. Eg: “partition_allocator/array_buffers/buffer1” refers to the child node “buffer1” in a graph structure of: root -> partition_allocator -> array_buffers -> buffer1.

weak: Option<bool>

A weak node means that the instrumentation that added the current node is unsure about the existence of the actual memory. Unless a “strong” (non-weak is default) node that has an edge to the current node exists in the current global dump, the current node will be discarded.

size_bytes: Option<u64>

Size of the node in bytes, used to compute the effective size of the nodes without double counting.

entries: Vec<MemoryNodeEntry>

Implementations

impl MemoryNode

pub fn id(&self) -> u64

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

pub fn absolute_name(&self) -> &str

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

pub fn weak(&self) -> bool

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

pub fn size_bytes(&self) -> u64

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

Trait Implementations

impl Clone for MemoryNode

fn clone(&self) -> MemoryNode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MemoryNode

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

Formats the value using the given formatter.

impl Default for MemoryNode

fn default() -> MemoryNode

Returns the “default value” for a type.

impl Message for MemoryNode

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 MemoryNode

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