Trait datafusion_execution::memory_pool::proxy::VecAllocExt

pub trait VecAllocExt {
    type T;

    // Required methods
    fn push_accounted(&mut self, x: Self::T, accounting: &mut usize);
    fn allocated_size(&self) -> usize;
}

Extension trait for Vec to account for allocations.

Required Associated Types

type T

Item type.

Required Methods

fn push_accounted(&mut self, x: Self::T, accounting: &mut usize)

Push new element to vector and store additional allocated bytes in accounting (additive).

fn allocated_size(&self) -> usize

Return the amount of memory allocated by this Vec (not recursively counting any heap allocations contained within the structure). Does not include the size of self
