Crate rancor

rancor

rancor provides scalable and efficient error handling without using type composition. This makes it best-suited for situations where:

• Programmatic error introspection is not useful
• Functions may error, but succeed most of the time
• Errors should provide as much useful detail as possible when emitted
• Use cases include both no_std and targets with support for std

Structs

• BoxedError
  An error type that preserves all detailed error messages. It is optimized to fit in a single pointer.
• Failure
  An error type that only preserves success or failure, throwing away any more detailed error messages.

Enums

• Infallible
  The error type for errors that can never happen.
• Panic
  An error type that does not occupy any space, panicking on creation instead.

Traits

• Context
  Helper methods for Contexts.
• Contextual
  An error type which can be given additional context.
• Error
  An error type which can be uniformly constructed from a StdError.
