Enum ReturnCode 

pub enum ReturnCode {
    Success,
    Error(ErrorCode),
}

Composite type for capturing success and error return codes. See Table 5 Return error codes

Clients can use ReturnCode to parse the result register value of a PSCI calls and easily determine if it was a success or an error.

Error codes are handled by the ErrorCode type. Having a separate type for errors helps using Result<(), ErrorCode>. If a single type would include both success and error values, then Err(ErrorCode::Success) would be incomprehensible.

Success

Error(ErrorCode)

Trait Implementations

impl Clone for ReturnCode

fn clone(&self) -> ReturnCode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ReturnCode

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

Formats the value using the given formatter.

impl From<ReturnCode> for i32

fn from(value: ReturnCode) -> Self

Converts to this type from the input type.

impl PartialEq for ReturnCode

fn eq(&self, other: &ReturnCode) -> 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 TryFrom<i32> for ReturnCode

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: i32) -> Result<Self, <Self as TryFrom<i32>>::Error>

Performs the conversion.

impl Copy for ReturnCode

impl Eq for ReturnCode

impl StructuralPartialEq for ReturnCode
