Struct freya::prelude::BorrowError

pub struct BorrowError {
    pub attempted_at: &'static Location<'static>,
    pub already_borrowed_at: Vec<&'static Location<'static>, Global>,
}

An error returned by [RefCell::try_borrow].

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

attempted_at: &'static Location<'static>

Debug-only location of attempted borrow

already_borrowed_at: Vec<&'static Location<'static>, Global>

Debug-only location of all current locations

Trait Implementations

impl Debug for BorrowError

impl Error for BorrowError

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type based access to context intended for error reports.
