Enum JitCompileError 

pub enum JitCompileError {
    Empty,
    FallsOffTheEnd,
    BadJumpTarget {
        op_index: usize,
        target: usize,
    },
    Assembly(String),
    Unsupported(&'static str),
}

Compile errors — structural, found before any code is emitted.

Variants

Empty

The program is empty.

FallsOffTheEnd

Execution can run off the end: the final op must be Return or Jump.

BadJumpTarget

A jump target is outside the program.

Fields

op_index: usize

Index of the offending op.

target: usize

The out-of-range target.

Assembly(String)

Assembly failed (missing hole/patch/map errors).

Unsupported(&'static str)

An op the per-piece stencil tier has no lowering for (e.g. MicroOp::StrAppend, which is emitted ONLY for the contiguous regalloc backend). The caller declines (falls back to bytecode), so this is never a hard failure — it just routes around the stencil tier.

Trait Implementations

impl Debug for JitCompileError

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

Formats the value using the given formatter.

impl Display for JitCompileError

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

Formats the value using the given formatter.

impl Error for JitCompileError

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 JitCompileError

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