Struct TestFilesystem

pub struct TestFilesystem { /* private fields */ }

Expand description

Filesystem implementation that records clear_cache calls for validating warm and cold benchmarks.

Implementations§

impl TestFilesystem

pub fn new() -> Self

pub async fn clear_cache_count(&self) -> u64

Trait Implementations§

impl CacheClearableFilesystem for TestFilesystem

fn clear_cache<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Clears all cached data in the filesystem. This method is used in “cold” benchmarks to ensure that the filesystem isn’t using cached data from the setup phase in the benchmark phase.

impl Clone for TestFilesystem

fn clone(&self) -> TestFilesystem

Returns a copy of the value. Read more

1.0.0 · Source§

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

Performs copy-assignment from source. Read more

impl Drop for TestFilesystem

fn drop(&mut self)

Executes the destructor for this type. Read more

impl Filesystem for TestFilesystem

fn shutdown<'async_trait>( self, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>
where Self: 'async_trait,

Cleans up the filesystem after a benchmark has run. Filesystem is unusable after this call.

fn benchmark_dir(&self) -> &Path

Path to where the filesystem is located in the current process’s namespace. All benchmark operations should happen within this directory.

Blanket Implementations§

impl<T> Any for T
where T: 'static + ?Sized,

fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more

impl<T> Borrow<T> for T
where T: ?Sized,

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more

impl<T> BorrowMut<T> for T
where T: ?Sized,

fn borrow_mut(&mut self) -> &mut T

Mutably borrows from an owned value. Read more

impl<T> BoxedFilesystem for T
where T: Filesystem,

fn shutdown_boxed<'a>( self: Box<T>, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'a>>
where T: 'a,

Filesystem::shutdown takes the filesystem by value which doesn’t work for Box<&dyn Filesystem> because the filesystem type isn’t known at compile time. Taking the filesystem as Box<Self> works and the type of the filesystem is now known so the Filesystem::shutdown method can be called.

impl<T> CloneToUninit for T
where T: Clone,

unsafe fn clone_to_uninit(&self, dst: *mut T)

🔬This is a nightly-only experimental API. (clone_to_uninit)

Performs copy-assignment from self to dst. Read more

impl<T, D> Encode<Ambiguous1, D> for T
where D: ResourceDialect,

unsafe fn encode( self, _encoder: &mut Encoder<'_, D>, _offset: usize, _depth: Depth, ) -> Result<(), Error>

Encodes the object into the encoder’s buffers. Any handles stored in the object are swapped for Handle::INVALID. Read more

impl<T, D> Encode<Ambiguous2, D> for T
where D: ResourceDialect,

unsafe fn encode( self, _encoder: &mut Encoder<'_, D>, _offset: usize, _depth: Depth, ) -> Result<(), Error>

Encodes the object into the encoder’s buffers. Any handles stored in the object are swapped for Handle::INVALID. Read more

impl<T> From<T> for T
