Struct HeapStatistics

#[repr(C)]
pub struct HeapStatistics(/* private fields */);

Collection of V8 heap information.

Instances of this class can be passed to v8::Isolate::GetHeapStatistics to get heap statistics from V8.

Implementations

impl HeapStatistics

pub fn total_heap_size(&self) -> usize

pub fn total_heap_size_executable(&self) -> usize

pub fn total_physical_size(&self) -> usize

pub fn total_available_size(&self) -> usize

pub fn total_global_handles_size(&self) -> usize
