Struct spinoso_env::ArgumentError
source · [−]pub struct ArgumentError(_);
Expand description
Error that indicates an argument parsing or value logic error occurred.
Argument errors have an associated message.
This error corresponds to the Ruby ArgumentError
Exception class.
Examples
let err = ArgumentError::new();
assert_eq!(err.message(), "ArgumentError");
let err = ArgumentError::with_message(
"bad environment variable name: contains null byte"
);
assert_eq!(err.message(), "bad environment variable name: contains null byte");
Implementations
sourceimpl ArgumentError
impl ArgumentError
sourcepub const fn new() -> Self
pub const fn new() -> Self
Construct a new, default argument error.
Examples
const ERR: ArgumentError = ArgumentError::new();
assert_eq!(ERR.message(), "ArgumentError");
sourcepub const fn with_message(message: &'static str) -> Self
pub const fn with_message(message: &'static str) -> Self
Construct a new, argument error with a message.
Examples
const ERR: ArgumentError = ArgumentError::with_message(
"bad environment variable name: contains null byte"
);
assert_eq!(ERR.message(), "bad environment variable name: contains null byte");
sourcepub const fn message(self) -> &'static str
pub const fn message(self) -> &'static str
Retrieve the exception message associated with this argument error.
Examples
let err = ArgumentError::new();
assert_eq!(err.message(), "ArgumentError");
let err = ArgumentError::with_message(
"bad environment variable name: contains null byte"
);
assert_eq!(err.message(), "bad environment variable name: contains null byte");
