Enum UserEditableSpan 

pub enum UserEditableSpan<T> {
    Direct(T),
    Recovered(T),
    MacroOnly,
}

The result of recovering a user-editable span from an ordered frame chain.

Variants

Direct(T)

The original frame was already user-editable.

Recovered(T)

A later frame recovered a user-editable span.

MacroOnly

No frame in the chain pointed at user-editable code.

Implementations

impl<T> UserEditableSpan<T>

pub fn into_option(self) -> Option<T>

Converts the recovery result into an optional recovered value.

Examples

use whitaker_common::rstest::UserEditableSpan;
use whitaker_common::span::{SourceLocation, SourceSpan};

let span = SourceSpan::new(SourceLocation::new(5, 1), SourceLocation::new(5, 7))
    .expect("example span should be valid");

assert_eq!(UserEditableSpan::Recovered(span).into_option(), Some(span));
assert_eq!(UserEditableSpan::<SourceSpan>::MacroOnly.into_option(), None);
