Enum conch_runtime::error::ExpansionError

pub enum ExpansionError {
    DivideByZero,
    NegativeExponent,
    BadAssig(String),
    EmptyParameter(String, String),
}

An error which may arise during parameter expansion.

Variants

DivideByZero

Attempted to divide by zero in an arithmetic subsitution.

NegativeExponent

Attempted to raise to a negative power in an arithmetic subsitution.

BadAssig(String)

Attempted to assign a special parameter, e.g. ${!:-value}.

EmptyParameter(String, String)

Attempted to evaluate a null or unset parameter, i.e. ${var:?msg}.
