1.0.0 · source

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

Converts this type into the (usually inferred) input type.

source

impl MachineStopType for ConstEvalErrKind

source

fn is_hard_err(&self) -> bool

If true, emit a hard error instead of going through the CONST_ERR lint

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
