Struct TransparentTestMemory 

pub struct TransparentTestMemory { /* private fields */ }

A memory provider that simply delegates 1:1 to the Rust global allocator.

This is meant for test scenarios where the minimal set of memory provider functionality is desired, to establish maximally controlled conditions.

For general-purpose public use, the GlobalPool should be used instead, as it is geared for actual efficiency - this here is just a simple passthrough implementation.

Implementations

impl TransparentTestMemory

pub const fn new() -> Self

Creates a new instance of the memory provider.

pub fn reserve(&self, len: usize) -> BytesBuf

Reserves len bytes of mutable memory, returning an empty BytesBuf whose capacity is backed by the reserved memory.

The memory reservation request will always be fulfilled, obtaining more memory from the operating system if necessary.

Zero-sized reservations

Reserving zero bytes of memory is a valid operation and will return a BytesBuf with zero or more bytes of capacity.

Panics

May panic if the operating system runs out of memory.

Trait Implementations

impl Clone for TransparentTestMemory

fn clone(&self) -> TransparentTestMemory

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TransparentTestMemory

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for TransparentTestMemory

fn default() -> TransparentTestMemory

Returns the “default value” for a type.

impl Memory for TransparentTestMemory

fn reserve(&self, min_bytes: usize) -> BytesBuf

Reserves at least min_bytes bytes of memory capacity.
