Trait RecordArena 

pub trait RecordArena<'a, Layout, RecordMut> {
    // Required method
    fn alloc(&'a mut self, layout: Layout) -> RecordMut;
}

Given some minimum layout of type Layout, the RecordArena should allocate a buffer, of size possibly larger than the record, and then return mutable pointers to the record within the buffer.

Required Methods

fn alloc(&'a mut self, layout: Layout) -> RecordMut

Allocates underlying buffer and returns a mutable reference RecordMut. Note that calling this function may not call an underlying memory allocation as the record arena may be virtual.
