Trait UniErrorOps 

pub trait UniErrorOps: UniDisplay + Deref<Target = dyn Error + Send + Sync + 'static> {
    // Required methods
    fn kind_code(&self) -> i32;
    fn kind_code2(&self) -> i32;

    // Provided method
    fn is_simple(&self) -> bool { ... }
}

A trait that specifies the operations that can be performed on a UniError.

Required Methods

fn kind_code(&self) -> i32

Returns the code (typically for FFI) for this specific kind

fn kind_code2(&self) -> i32

Returns a 2nd code (typically for FFI) for this specific kind.

fn kind_value(&self) -> Cow<'static, str>

The string value of the kind, if any. This is useful for programmatic evaluation when the type is boxed in the error chain and the type is not known

fn kind_context_str(&self) -> Option<Cow<'static, str>>

Returns additional context for this specific kind, if any

fn prev_cause<'e>(&'e self) -> Option<Cause<'e>>

Returns a reference to the first entry in the cause chain.

fn chain(&self) -> Chain<'_>

Returns an iterator over the cause chain.

fn root_cause(&self) -> Option<Cause<'_>>

Returns the root cause of this error. If None is returned then this error is the root cause.

Provided Methods

fn is_simple(&self) -> bool

Returns true if the error is a SimpleError.

Implementations

pub fn downcast_ref<K: UniKind + ?Sized>(&self) -> Option<&UniError<K>>
