Struct MemorySnapshot 

pub struct MemorySnapshot {
    pub timestamp: u64,
    pub stats: MemoryStats,
    pub active_allocations: HashMap<usize, ActiveAllocation>,
    pub active_bindings: Option<Vec<SnapshotBinding>>,
    pub thread_stats: HashMap<u64, ThreadMemoryStats>,
}

One of several same-named MemorySnapshot types in this crate: this one is the the canonical point-in-time projection built by the snapshot engine.

Convert at the module boundary instead of passing it across; a global rename is deliberately avoided (see DATA_ACCURACY_DEVELOPMENT_PLAN §14.2). Memory snapshot - a point-in-time view of memory usage

Fields

timestamp: u64

Timestamp when this snapshot was taken

stats: MemoryStats

Overall memory statistics

active_allocations: HashMap<usize, ActiveAllocation>

Compatibility address lookup; returns the newest binding at an address.

active_bindings: Option<Vec<SnapshotBinding>>

Lossless identity-bearing projection. None denotes a legacy address-only snapshot.

thread_stats: HashMap<u64, ThreadMemoryStats>

Per-thread statistics

Implementations

impl MemorySnapshot

pub fn new() -> Self

Create a new empty snapshot

pub fn from_allocation_infos(allocations: Vec<AllocationInfo>) -> Self

Build a MemorySnapshot from a list of AllocationInfo (capture module type)

pub fn active_count(&self) -> usize

Get the number of active allocations

pub fn allocations(&self) -> impl Iterator<Item = &ActiveAllocation>

Iterate all bindings, including overlapping generations at the same address. Legacy snapshots continue to use their address-only map.

pub fn current_memory(&self) -> usize

Get the current memory usage

pub fn peak_memory(&self) -> usize

Get the peak memory usage

Trait Implementations

impl Clone for MemorySnapshot

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MemorySnapshot

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

Formats the value using the given formatter.

impl Default for MemorySnapshot

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for MemorySnapshot

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for MemorySnapshot

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
