Enum PipelineError 

#[non_exhaustive]
pub enum PipelineError {
    IoUringSyscall {
        syscall: &'static str,
        errno: i32,
        fix: &'static str,
    },
    QueueFull {
        queue: &'static str,
        fix: &'static str,
    },
    NotLinux,
    NvmePassthroughDisabled,
    Backend(String),
}

Errors surfaced by the runtime layer. Every variant carries a Fix:-bearing message so a reviewer can act on the failure.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

IoUringSyscall

Raw io_uring / libc syscall failed with an errno.

Fields

syscall: &'static str

Which syscall failed (io_uring_setup, mmap, io_uring_enter).

errno: i32

Underlying errno value.

fix: &'static str

Actionable remediation.

QueueFull

io_uring submission or completion queue was full / overflowed.

Fields

queue: &'static str

“submission” or “completion”.

fix: &'static str

Actionable remediation.

NotLinux

Attempted to use io_uring on a non-Linux platform.

NvmePassthroughDisabled

Feature required for NVMe passthrough is not enabled.

Backend(String)

Backend error bubbled up from compile or dispatch.

Trait Implementations

impl Clone for PipelineError

fn clone(&self) -> PipelineError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PipelineError

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

Formats the value using the given formatter.

impl Display for PipelineError

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

Formats the value using the given formatter.

impl Error for PipelineError

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 From<BackendError> for PipelineError

fn from(err: BackendError) -> Self

Converts to this type from the input type.

impl From<PipelineError> for TenantError

fn from(source: PipelineError) -> Self

Converts to this type from the input type.

impl From<ReplayLogError> for PipelineError

Let callers bridge ReplayLogError into the unified PipelineError surface when driving the log from the megakernel pump loop.

fn from(err: ReplayLogError) -> Self

Converts to this type from the input type.
