Struct IoFault 

pub struct IoFault {
    pub source: &'static str,
    pub code: Option<ErrorCode>,
    pub error: Arc<Error>,
}

A fault, as the layer that observed it reported it (DI-D-50): what failed an operation or a commit, relayed with where it came from.

Two faults are equal when they name the same source and code and carry the same report – the one shared Arc, as a marking and the completion it records share it – since an io::Error has no equality of its own.

Fields

source: &'static str

The layer that reported it: "windows-ioring" for dioring over Windows.

code: Option<ErrorCode>

The layer’s code for it, where it gives one. Its meaning is the source’s: an HRESULT from the Windows backend, which always gives one.

error: Arc<Error>

The layer’s own report.

Trait Implementations

impl Clone for IoFault

fn clone(&self) -> IoFault

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IoFault

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

Formats the value using the given formatter.

impl Display for IoFault

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

Formats the value using the given formatter.

impl Eq for IoFault

impl Error for IoFault

So a driver can hand a fault to a consumer as the source of an io::Error that downcasts back to it, as a RefusalCause does.

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

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

Provides type-based access to context intended for error reports.

impl PartialEq for IoFault

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

Equality operator ==.

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

Inequality operator !=.
