The error type.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

InvalidName(String, String, String, String)

The name of the ident is invalid.

• The first argument is the invalid name.
• The second argument is the reason.
• The third argument is the valid name.
• The fourth argument is the statement type.

InvalidMainFunction(String, String)

The main function is invalid.

• The first argument is the reason.
• The second argument is the help message.

UnDeclaredIdent(String)

The ident is undeclared.

• The first argument is the name of the ident.

AlreadyDeclared(String, (usize, usize))

Alreade decleared function.

• The first argument is the name of the ident.
• The second argument is the span of the old declaration. (The span of the new declaration is stored in the error.)

MissingMainFunction

Missing main function. (The span of the error will not be used.)

InvalidExitCode(BigDecimal)

The exit code is invalid.

• The first argument is the exit code.

NotCallable((usize, usize))

The ident is not callable.

• The first argument is the span of the call (The span of the error is the not callable ident.)

UncorrectArguments(usize, (usize, usize), Vec<Param>, String)

Uncorrect arguments.

• The first argument is the number of arguments.
• The second argument is the span of the called function.
• The third argument is the parametets of the called function.
• The forth argument is the name of the called function. (The span of the error is the function call expression.)

UnexpectedType(String, String)

Unexpected type.

• The first argument is the expected type.
• The second argument is the actual type. (The span of the error is the expression.)

MultiplePackedParams(String)

Multiple packed params.

• The first argument is the name of the function. (The span of the error is the parametets of the function.)

PackedParamNotLast(String)

Packed param is not last.

• The first argument is the name of the packed param. (The span of the error is the packed param.)

MultipleParamsWithTheSameName(String, String)

Multiple params with the same name.

• The first argument is the name of the param.
• The second argument is the name of the function. (The span of the error is the parametets of the function.)

InvalidUnpackArg(String)

Invalid unpacked argument.

• The first argument is the name of the argument type.

FormatError(String, String)

Format error.

• The first argument is the reason.
• The second argument is the help message.

Runtime(String)

Runtime error. (The error is not a bug in the interpreter.)

• The first argument is the reason.

Parse(String)

The parser error.
