Conformance test harnesses will implement this protocol to setup its associated filesystem servers with the described directory layout, allowing their implementation of fuchsia.io and fuchsia.io2 protocols to be verified by a common test suite.

Different test cases will not interact with one another during the conformance test, and only one test case will be active at a time per tested filesystem. So it is possible to host all cases as different sub-directories under a common filesystem instance, to simplify the lifecycle and implementation.

If a test case has mutable bits, each method call should be implemented to obtain the directory in its original state. In other words, repeated test case set up should “as-if” yield new directories.

See src/storage/conformance/README.md for an overview of io conformance testing.

Io1Config lets the test harness modulate the set of expected outcomes and behaviors validated by the test suite, by declaring specific properties about the filesystem implementation. For example, setting [ImmutableFile] to true informs the test suites that files hosted by this harness do not support mutation.

Trait Implementations

impl Clone for Io1Config

fn clone(&self) -> Io1Config

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Io1Config

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

Formats the value using the given formatter.

impl Decode<Io1Config> for Io1Config

fn new_empty() -> Self

Creates a valid instance of Self. The specific value does not matter, since it will be overwritten by decode.

unsafe fn decode( &mut self, decoder: &mut Decoder<'_>, offset: usize, depth: Depth ) -> Result<()>

Decodes an object of type T from the decoder’s buffers into self.

impl Default for Io1Config

fn default() -> Io1Config

Returns the “default value” for a type.

impl Encode<Io1Config> for &Io1Config

unsafe fn encode( self, encoder: &mut Encoder<'_>, offset: usize, depth: Depth ) -> Result<()>

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

impl PartialEq for Io1Config

fn eq(&self, other: &Io1Config) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TypeMarker for Io1Config

type Owned = Io1Config

The owned Rust type which this FIDL type decodes into.

fn inline_align(_context: Context) -> usize

Returns the minimum required alignment of the inline portion of the encoded object. It must be a (nonzero) power of two.

fn inline_size(_context: Context) -> usize

Returns the size of the inline portion of the encoded object, including padding for alignment. Must be a multiple of inline_align.

fn encode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and encoding requires no validation. When true, we can optimize encoding arrays and vectors of Self::Owned to a single memcpy.

fn decode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and decoding requires no validation. When true, we can optimize decoding arrays and vectors of Self::Owned to a single memcpy.

impl ValueTypeMarker for Io1Config

type Borrowed<'a> = &'a Io1Config

The Rust type to use for encoding. This is a particular Encode<Self> type cheaply obtainable from &Self::Owned. There are three cases:

fn borrow<'a>(value: &'a <Self as TypeMarker>::Owned) -> Self::Borrowed<'a>

Cheaply converts from &Self::Owned to Self::Borrowed.

impl Persistable for Io1Config

impl StructuralPartialEq for Io1Config
