Enum DeclarationError

pub enum DeclarationError {
    AlreadyDeclared,
    NoValueAvailable,
    OverrideValueTypeMismatch,
    PriorValueTypeMismatch,
    InitialValueOutOfRange,
    InvalidRange,
}

Error that can be generated when doing operations on parameters.

Variants

AlreadyDeclared

Parameter was already declared and a new declaration was attempted.

NoValueAvailable

Parameter was declared as non optional but no value was available, either through a user specified default, a command-line override, or a previously set value.

OverrideValueTypeMismatch

The override value that was provided has the wrong type. This error is bypassed when using ParameterBuilder::ignore_override().

PriorValueTypeMismatch

The value that the parameter was already set to has the wrong type. This error is bypassed when using ParameterBuilder::discard_mismatching_prior_value.

InitialValueOutOfRange

The initial value that was selected is out of range.

InvalidRange

An invalid range was provided to a parameter declaration (i.e. lower bound > higher bound).
