Enum DecodeScanFuseError 

pub enum DecodeScanFuseError {
    HandoffBufferMissing {
        handoff: String,
    },
    ZeroHandoff {
        handoff: String,
    },
    Fusion(FusionError),
}

Error states surfaced by fuse_decode_scan.

Variants

HandoffBufferMissing

The caller supplied &decoder and &scanner but neither declares the named handoff buffer. Fusing would produce a Program with no shared byte-flow path - the caller’s intent cannot be honoured.

Fields

handoff: String

Name of the missing decoder/scanner handoff buffer.

ZeroHandoff

The caller passed handoff_byte_count = 0. Workgroup allocations must be strictly positive or the fused Program declares a zero-sized shared buffer that every driver rejects. Returning an error instead of asserting (per PHASE2_DECODE HIGH / LAW 5) keeps adversarial callers from crashing the driver process.

Fields

handoff: String

Name of the handoff buffer whose capacity was zero.

Fusion(FusionError)

fuse_programs rejected the pair (self-aliasing or workgroup-size mismatch). The inner error is the original.

Trait Implementations

impl Debug for DecodeScanFuseError

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

Formats the value using the given formatter.

impl Display for DecodeScanFuseError

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

Formats the value using the given formatter.

impl Error for DecodeScanFuseError

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<FusionError> for DecodeScanFuseError

fn from(source: FusionError) -> Self

Converts to this type from the input type.
