Enum ConstError 

pub enum ConstError {
    Arity {
        name: String,
        expected: usize,
        got: usize,
    },
    LevelNotClosed {
        name: String,
        level: String,
    },
    SPropLevel {
        name: String,
    },
}

Why a Term::Const reference could not be resolved. Every kernel and the reducer report the same three failures, so a reference refused by typing is never a normal form to the reducer.

Variants

Arity

The level list does not match the declaration’s telescope.

Fields

name: String

expected: usize

got: usize

LevelNotClosed

The declaration’s stored type mentions a level variable its parameter list does not bind. Instantiating it would leave that level free, so the declaration is refused outright.

Fields

name: String

level: String

SPropLevel

A level argument is or contains SProp, which is a sort and never a level.

Fields

name: String

Trait Implementations

impl Clone for ConstError

fn clone(&self) -> ConstError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConstError

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

Formats the value using the given formatter.

impl Display for ConstError

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

Formats the value using the given formatter.

impl PartialEq for ConstError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
