Enum CallError

pub enum CallError {
    ArgumentError(LineCol, String),
    EvalError(LineCol, String),
    InternalError(LineCol, String),
    IoError(Error),
    NestedError(String),
    SyntaxError,
}

Command or function execution errors.

These are separate from the more generic Error type because they are not annotated with the specific callable that triggered the error. We add such annotation once we capture the error within the evaluation logic.

Variants

ArgumentError(LineCol, String)

A specific parameter had an invalid value.

EvalError(LineCol, String)

Error while evaluating input arguments.

InternalError(LineCol, String)

Any other error not representable by other values.

IoError(Error)

I/O error during execution.

NestedError(String)

Hack to support errors that arise from within a program that is RUN.

SyntaxError

General mismatch of parameters given to the function with expectations (different numbers, invalid types).
