Enum LowerError 

pub enum LowerError {
    UnsupportedOp {
        block: String,
        op: Op,
    },
    OutOfBoundsMemory {
        block: String,
    },

        block: String,
        first: ElemType,
        second: ElemType,
    },
}

Errors produced by the lowering pass.

Variants

UnsupportedOp

The block contained operations the lowering pass doesn’t yet handle.

Fields

block: String

Block name from BlockIR::name.

op: Op

The op the lowering didn’t know how to handle.

OutOfBoundsMemory

The lowering refused because of a memory-safety concern (e.g. an out-of-bounds load pattern).

Fields

block: String

Block name.

MixedElementTypes

jit CRITICAL fix: the block mixed SIMD element types (e.g. an f32x4.add next to an i32x4.add). The flat blueprint op stream has a single load/store element width inferred from the block’s SIMD ops, so a heterogeneous block cannot be lowered without miscompiling the loads/stores. We fail closed; the caller keeps the function on the CPU path.

Fields

block: String

Block name.

first: ElemType

First element type seen.

second: ElemType

Conflicting element type seen later.

Trait Implementations

impl Debug for LowerError

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

Formats the value using the given formatter.

impl Display for LowerError

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

Formats the value using the given formatter.

impl Error for LowerError

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 LowerError

fn eq(&self, other: &LowerError) -> 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.
