Expand description

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.

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

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