Variants

NoSuchVariable(String)

An attempt to use a variable that does not exist.

WrongInputCount(usize, usize)

The constraint satisfaction method received too few or too many values as input.

WrongOutputCount(usize, usize)

The constraint satisfaction method returned too few or too many values as output.

MutabilityMismatch(MutabilityMismatch)

Unexpected mutability of an argument.

TypeConversionFailure(&'static str, &'static str)

Failure to convert a variable into the specified type.

Custom(String)

A custom error from the programmer.
