Struct Unsupported 

pub struct Unsupported {
    pub inst: Inst,
    pub term: Option<&'static str>,
}

Why a function could not be lowered.

One instruction and then nothing. A function with no rule for something in it is a function this cannot finish, and the second thing it could not lower is not news.

Fields

inst: Inst

The instruction that stopped it.

term: Option<&'static str>

What the rule file would call it, or nothing if the rule language has no name for it at all, which is what an instruction at a width nothing is written about looks like.

Trait Implementations

impl Clone for Unsupported

fn clone(&self) -> Unsupported

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Unsupported

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

Formats the value using the given formatter.

impl Display for Unsupported

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

Formats the value using the given formatter.

impl Eq for Unsupported

impl Error for Unsupported

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 Unsupported

fn eq(&self, other: &Unsupported) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
