Enum 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}.

Trait Implementations

impl Clone for ExpansionError

fn clone(&self) -> ExpansionError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ExpansionError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for ExpansionError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for ExpansionError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<ExpansionError> for RuntimeError

fn from(source: ExpansionError) -> Self

Converts to this type from the input type.

impl IsFatalError for ExpansionError

fn is_fatal(&self) -> bool

Checks whether the error should be considered a “fatal” error.

impl PartialEq for ExpansionError

fn eq(&self, other: &ExpansionError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
