Enum AccessError 

pub enum AccessError {
    UnsupportedMode,
    BorrowConflict,
    Poisoned,
}

Errors that can occur when accessing shared containers.

Variants

UnsupportedMode

The requested operation is not supported for this container type.

This typically occurs when trying to use synchronous methods on an async container, or vice versa.

BorrowConflict

A borrow conflict occurred (for single-threaded RefCell-based containers).

This happens when trying to acquire a write lock while a read lock exists, or when trying to acquire any lock while a write lock exists.

Poisoned

The lock was poisoned due to a panic while holding the lock.

This only occurs with multi-threaded RwLock-based containers.

Trait Implementations

impl Clone for AccessError

fn clone(&self) -> AccessError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AccessError

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

Formats the value using the given formatter.

impl Display for AccessError

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

Formats the value using the given formatter.

impl Error for AccessError

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

Returns 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.

impl PartialEq for AccessError

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

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
