Enum ComponentAccessError 

pub enum ComponentAccessError {
    NotRegistered {
        resource: &'static str,
        operation: &'static str,
    },
    ReadConflict {
        resource: &'static str,
        operation: &'static str,
    },
    WriteConflict {
        resource: &'static str,
        operation: &'static str,
    },
}

Failure to acquire access to component state.

A conflict identifies the requested access, not the holder or its call stack. Callback reentry can cause a conflict, but is not the only possible cause.

Variants

NotRegistered

Registration has not supplied the requested resource.

Fields

resource: &'static str

The resource being accessed.

operation: &'static str

The attempted operation.

ReadConflict

Shared access conflicts with an existing exclusive borrow.

Fields

resource: &'static str

The resource being accessed.

operation: &'static str

The attempted operation.

WriteConflict

Exclusive access conflicts with an existing shared or exclusive borrow.

Fields

resource: &'static str

The resource being accessed.

operation: &'static str

The attempted operation.

impl Eq for ComponentAccessError

impl Error for ComponentAccessError

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
