Enum RewriteError 

pub enum RewriteError {
    Parse(String),
    Lower(String),
    Reencode(String),
    Trampoline(String),
}

Errors raised by the rewriter.

Variants

Parse(String)

The Wasm bytes failed to parse.

Lower(String)

The lower→emit pipeline rejected a candidate (e.g. unsupported op). The candidate is silently skipped — this variant is returned only when the rewriter is configured to be strict (currently never, but reserved).

Reencode(String)

Re-encoding the module failed.

Trampoline(String)

An offload candidate’s signature couldn’t be safely synthesised as a trampoline (e.g. unsupported result type). The candidate is skipped rather than producing invalid Wasm.

Trait Implementations

impl Debug for RewriteError

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

Formats the value using the given formatter.

impl Display for RewriteError

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

Formats the value using the given formatter.

impl Error for RewriteError

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<E: Display> From<Error<E>> for RewriteError

fn from(e: Error<E>) -> Self

Converts to this type from the input type.
