pub enum InvalidBorrow {
    Mutable,
    Immutable,
}

Error indicating that accessing the requested Resource in a Resources container via get or get_mut methods would violate borrow rules.

Variants

Can't access mutably because the resource is accessed either immutably or mutably elsewhere.

Immutable

Can't access immutably because the resource is accessed mutably elsewhere.

Trait Implementations

impl Clone for InvalidBorrow

fn clone(&self) -> InvalidBorrow

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for InvalidBorrow

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Display for InvalidBorrow

fn fmt(&self, f: &mut Formatter) -> FmtResult

Formats the value using the given formatter.

impl Eq for InvalidBorrow

impl Error for InvalidBorrow

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

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

fn backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl From<InvalidBorrow> for CantGetResource

fn from(error: InvalidBorrow) -> Self

Performs the conversion.

impl PartialEq<InvalidBorrow> for InvalidBorrow

fn eq(&self, other: &InvalidBorrow) -> bool

This method tests for self and other values to be equal, and is used by ==.

#[must_use]fn ne(&self, other: &Rhs) -> bool

This method tests for !=.
