Enum rustc_mir::interpret::UnsupportedOpInfo[−][src]

pub enum UnsupportedOpInfo {
    Unsupported(String),
    NoMirFor(DefId),
    ReadPointerAsBytes,
    ReadBytesAsPointer,
    ThreadLocalStatic(DefId),
    ReadExternStatic(DefId),
}

Expand description

Error information for when the program did something that might (or might not) be correct to do according to the Rust spec, but due to limitations in the interpreter, the operation could not be carried out. These limitations can differ between CTFE and the Miri engine, e.g., CTFE does not support dereferencing pointers at integral addresses.

Variants

Unsupported(String)

Free-form case. Only for errors that are never caught!

NoMirFor(DefId)

Could not find MIR for a function.

ReadPointerAsBytes

Encountered a pointer where we needed raw bytes.

ReadBytesAsPointer

Encountered raw bytes where we needed a pointer.

ThreadLocalStatic(DefId)

Accessing thread local statics

ReadExternStatic(DefId)

Accessing an unsupported extern static.

Layout

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