Enum ConnectionFailureReason

#[non_exhaustive]
pub enum ConnectionFailureReason {
    AdapterUnavailable,
    OutOfRange,
    Rejected,
    Timeout,
    AlreadyConnected,
    PairingFailed,
    BleError(String),
    Other(String),
}

Structured reasons for connection failures.

This enum is marked #[non_exhaustive] to allow adding new reasons in future versions without breaking downstream code.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

AdapterUnavailable

Bluetooth adapter not available or powered off.

OutOfRange

Device is out of range.

Rejected

Device rejected the connection.

Timeout

Connection attempt timed out.

AlreadyConnected

Already connected to another central.

PairingFailed

Pairing failed.

BleError(String)

Generic BLE error.

Other(String)

Other/unknown error.

Trait Implementations

impl Clone for ConnectionFailureReason

fn clone(&self) -> ConnectionFailureReason

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConnectionFailureReason

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

Formats the value using the given formatter.

impl Display for ConnectionFailureReason

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

Formats the value using the given formatter.

impl PartialEq for ConnectionFailureReason

fn eq(&self, other: &ConnectionFailureReason) -> 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.
