Struct ProcessMemoryStats 

pub struct ProcessMemoryStats {
    pub process_rss_bytes: Option<u64>,
    pub process_vm_size_bytes: Option<u64>,
}

Memory stats of the hosting OS process. Shared by host and proc introspection surfaces — both agents are authoritative for the OS process they run in.

In the common one-proc-per-process deployment these read like “proc memory”. In multi-proc-per-process setups, co-hosted procs report the same hosting-process values.

Fields

process_rss_bytes: Option<u64>

RSS of the hosting OS process (bytes). None on non-Linux or read failure (PD-2).

process_vm_size_bytes: Option<u64>

Virtual memory size of the hosting OS process (bytes). None on non-Linux or read failure (PD-2).

Implementations

impl ProcessMemoryStats

pub fn read_from_procfs() -> Self

Read the hosting OS process memory stats from procfs. Returns ProcessMemoryStats with None fields on non-Linux or any read/parse failure (PD-2: never fabricated).

pub fn from_attrs(attrs: &Attrs) -> Self

pub fn to_attrs(&self, attrs: &mut Attrs)

Trait Implementations

impl Clone for ProcessMemoryStats

fn clone(&self) -> ProcessMemoryStats

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProcessMemoryStats

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

Formats the value using the given formatter.

impl Default for ProcessMemoryStats

fn default() -> ProcessMemoryStats

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ProcessMemoryStats

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Named for ProcessMemoryStats

fn typename() -> &'static str

The globally unique type name for the type. This should typically be the fully qualified Rust name of the type.

fn typehash() -> u64

A globally unique hash for this type. TODO: actually enforce perfect hashing

fn typeid() -> TypeId

The TypeId for this type. TypeIds are unique only within a binary, and should not be used for global identification.

fn port() -> u64

The globally unique port for this type. Typed ports are in the range of 1<<63..1<<64-1.

fn arm(&self) -> Option<&'static str>

If the named type is an enum, this returns the name of the arm of the value self.

unsafe fn arm_unchecked(self_: *const ()) -> Option<&'static str>

An unsafe version of ‘arm’, accepting a pointer to the value, for use in type-erased settings.

impl PartialEq for ProcessMemoryStats

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

impl Serialize for ProcessMemoryStats

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
