pub struct IOError { /* private fields */ }
Expand description
Ruby IOError
error type.
Descendants of class Exception
are used to communicate between
Kernel#raise
and rescue
statements in begin ... end
blocks.
Exception objects carry information about the exception – its type (the
exception’s class name), an optional descriptive string, and optional
traceback information. Exception
subclasses may add additional information
like NameError#name
.
Implementations§
source§impl IOError
impl IOError
sourcepub const fn new() -> Self
pub const fn new() -> Self
Construct a new, default IOError
Ruby exception.
This constructor sets the exception message to IOError
.
§Examples
let exception = IOError::new();
assert_eq!(exception.message(), b"IOError");
sourcepub const fn with_message(message: &'static str) -> Self
pub const fn with_message(message: &'static str) -> Self
Construct a new, IOError
Ruby exception with the given
message.
§Examples
let exception = IOError::with_message("an error occurred");
assert_eq!(exception.message(), b"an error occurred");
