Crate spinoso_exception

source · [−]

Expand description

Built in Ruby exception types.

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.

Ruby Exception Hierarchy

The built-in subclasses of Exception are:

NoMemoryError
ScriptError
SecurityError
SignalException
- Interrupt
StandardError — default for rescue
- ArgumentError
  - UncaughtThrowError
- EncodingError
- FiberError
- IOError
  - EOFError
- IndexError
  - KeyError
  - StopIteration
- LocalJumpError
- NameError
  - NoMethodError
- RangeError
  - FloatDomainError
- RegexpError
- RuntimeError — default for raise
  - FrozenError
- SystemCallError
  - Errno::*
- ThreadError
- TypeError
- ZeroDivisionError
SystemExit
SystemStackError
fatal — impossible to rescue

`no_std`

This crate is no_std compatible when built without the std feature. This crate has a required dependency on alloc.

Crate features

All features are enabled by default.

std - Enables a dependency on the Rust Standard Library. Activating this feature enables std::error::Error impls on error types in this crate.
