Enum LoweringRefusal 

pub enum LoweringRefusal {
    CompilerSemantics {
        build: CompilerSemantics,
        bound: CompilerSemantics,
    },
    MissingCapability {
        capability: String,
    },
}

Why a profile cannot lower a plan for a key.

Variants

CompilerSemantics

The plan’s indices are only meaningful under the lowering that produced them, and this profile lowers other semantics.

Fields

build: CompilerSemantics

bound: CompilerSemantics

MissingCapability

The plan needs a lowering capability this profile does not declare.

Fields

capability: String

Trait Implementations

impl Clone for LoweringRefusal

fn clone(&self) -> LoweringRefusal

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LoweringRefusal

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

Formats the value using the given formatter.

impl Display for LoweringRefusal

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

Formats the value using the given formatter.

impl Eq for LoweringRefusal

impl Error for LoweringRefusal

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 LoweringRefusal

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

Equality operator ==.

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

Inequality operator !=.
