Status codes for binder operations.

Represents various error conditions that can occur during binder IPC operations, including system errors, protocol errors, and application-specific errors.

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.

Ok

Operation completed successfully

Unknown

Unknown error occurred

NoMemory

Out of memory

InvalidOperation

Invalid operation for current state

BadValue

Invalid parameter value

BadType

Wrong data type

NameNotFound

Named resource not found

PermissionDenied

Permission denied

NoInit

Object not initialized

AlreadyExists

Resource already exists

DeadObject

Remote object is dead

FailedTransaction

Transaction failed

UnknownTransaction

Unknown transaction code

BadIndex

Invalid array index

FdsNotAllowed

File descriptors not allowed

UnexpectedNull

Unexpected null pointer

NotEnoughData

Not enough data available

WouldBlock

Operation would block

TimedOut

Operation timed out

BadFd

Bad file descriptor

Errno(i32)

System errno value

ServiceSpecific(i32)

Service-specific error code

Trait Implementations

impl Clone for StatusCode

fn clone(&self) -> StatusCode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StatusCode

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

Formats the value using the given formatter.

impl Default for StatusCode

fn default() -> StatusCode

Returns the “default value” for a type.

impl Deserialize for StatusCode

fn deserialize(parcel: &mut Parcel) -> Result<Self>

Deserialize an instance from the given Parcel.

fn deserialize_from(&mut self, parcel: &mut Parcel) -> Result<()>

Deserialize an instance from the given Parcel onto the current object. This operation will overwrite the old value partially or completely, depending on how much data is available.

impl Display for StatusCode

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

Formats the value using the given formatter.

impl Error for StatusCode

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 From<Errno> for StatusCode

fn from(errno: Errno) -> Self

Converts to this type from the input type.

impl From<Error> for StatusCode

fn from(_: Error) -> Self

Converts to this type from the input type.

impl From<ExceptionCode> for StatusCode

fn from(exception: ExceptionCode) -> Self

Converts to this type from the input type.

impl From<Status> for StatusCode

fn from(status: Status) -> Self

Converts to this type from the input type.

impl From<StatusCode> for ExceptionCode

fn from(status: StatusCode) -> Self

Converts to this type from the input type.

impl From<StatusCode> for Status

fn from(status: StatusCode) -> Self

Converts to this type from the input type.

impl From<StatusCode> for i32

fn from(code: StatusCode) -> Self

Converts to this type from the input type.

impl From<TryFromSliceError> for StatusCode

fn from(_: TryFromSliceError) -> Self

Converts to this type from the input type.

impl From<i32> for StatusCode

fn from(code: i32) -> Self

Converts to this type from the input type.

impl Hash for StatusCode

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for StatusCode

fn cmp(&self, other: &StatusCode) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for StatusCode

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

impl PartialOrd for StatusCode

fn partial_cmp(&self, other: &StatusCode) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for StatusCode

fn serialize(&self, parcel: &mut Parcel) -> Result<()>

Serialize this instance into the given Parcel.

impl Copy for StatusCode

impl Eq for StatusCode

impl StructuralPartialEq for StatusCode
