Enum SpecializationError 

pub enum SpecializationError {
    WrongInputCount {
        expected: usize,
        actual: usize,
    },
    AxisOutOfRange {
        input: usize,
        axis: u32,
        rank: usize,
    },
    AlignmentUnavailable {
        input: usize,
        required_alignment_log2: u8,
    },
    ProjectionOverflow {
        input: usize,
        rank: usize,
    },
}

Reports failures while projecting signatures through specialization requirements.

Examples

use tenferro_runtime::{InputSignature, SpecializationRequirements};

let error = SpecializationRequirements::polymorphic(1)
    .project(&InputSignature::new(Vec::new()))
    .unwrap_err();
assert!(matches!(error, tenferro_runtime::PrepareError::Specialization { .. }));

Variants

WrongInputCount

The signature does not have the required input arity.

Fields

expected: usize

Required input count.

actual: usize

Actual input count.

AxisOutOfRange

A concrete-axis request names an axis outside the actual rank.

Fields

input: usize

Input position in the signature.

axis: u32

Requested axis.

rank: usize

Actual rank.

AlignmentUnavailable

A required host-pointer alignment class is unavailable.

Fields

input: usize

Input position in the signature.

required_alignment_log2: u8

Required base-2 logarithm alignment class.

ProjectionOverflow

A specialization projection could not encode every requested axis in the finite public axis type.

Fields

input: usize

Input position in the signature.

rank: usize

Rank that could not be encoded.

Trait Implementations

impl Clone for SpecializationError

fn clone(&self) -> SpecializationError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SpecializationError

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

Formats the value using the given formatter.

impl Display for SpecializationError

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

Formats the value using the given formatter.

impl Error for SpecializationError

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 SpecializationError

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

Tests for self and other values to be equal, and is used by ==.

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

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