Struct SpanRecoveryFrame 

pub struct SpanRecoveryFrame<T> { /* private fields */ }

A single span-recovery frame and whether it still comes from macro expansion.

Implementations

impl<T> SpanRecoveryFrame<T>

pub const fn new(value: T, from_expansion: bool) -> Self

Builds a recovery frame from a value and expansion flag.

Examples

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

let span = SourceSpan::new(SourceLocation::new(3, 1), SourceLocation::new(3, 8))
    .expect("example span should be valid");
let frame = SpanRecoveryFrame::new(span, true);

assert!(frame.from_expansion());

pub const fn value(&self) -> &T

Returns the stored frame value.

pub fn into_value(self) -> T

Consumes the frame and returns the stored value.

pub const fn from_expansion(&self) -> bool

Returns whether the frame still originates from macro expansion.
