Source§type TypedStats<'b> = AnyStats<'b>
where
Self: 'b
type TypedStats<'b> = AnyStats<'b> where Self: 'b
The type returned by the stats method.
Source§fn typed_stats(&self) -> AnyStats<'_>
fn typed_stats(&self) -> AnyStats<'_>
Returns a type which provides statistics about the memory usage of the bump allocator.

fn reserve(&self, additional: usize)
Reserves capacity for at least
additional more bytes to be bump allocated.
The bump allocator may reserve more space to avoid frequent reallocations.
After calling reserve, self.stats().remaining() will be greater than or equal to
additional. Does nothing if the capacity is already sufficient. Read moreSource§fn try_reserve(&self, additional: usize) -> Result<(), AllocError>
