Performs copy-assignment from source. Read more

source

impl<T> Default for MemCounter<T>

source

fn default() -> Self

Returns the “default value” for a type. Read more

source

impl<T: MallocSizeOf> MemTracker<T> for MemCounter<T>

source

fn on_remove(&mut self, value: &T)

Update malloc_size_of when a value is removed.

source

fn on_insert(&mut self, value: &T)

Update malloc_size_of when a value is inserted.

source

fn on_clear(&mut self)

Reset malloc_size_of to zero.

source

source

impl<T: PartialEq> PartialEq<MemCounter<T>> for MemCounter<T>

source

fn eq(&self, other: &MemCounter<T>) -> bool

This method tests for self and other values to be equal, and is used by ==. Read more

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason. Read more
