Enum Error 

pub enum Error {
    NullHandle,
    InvalidArgument(&'static str),
    CString(NulError),
    Native {
        operation: &'static str,
        code: i32,

    },
}

Error types and helpers used by the public API. Errors returned by the safe wrapper.

Variants

NullHandle

The native runtime returned a null handle during construction.

InvalidArgument(&'static str)

A wrapper-side argument validation failure.

CString(NulError)

A string contained an interior nul byte before crossing the FFI boundary.

Native

A native operation returned a non-zero status code.

Fields

operation: &'static str

The operation that failed.

code: i32

The raw native status code.

message: String

Human-readable description of the status code.

ResourceExists(String)

A resource with the given id already exists.

ResourceNotFound(String)

A resource with the given id could not be found.

ResourceTypeMismatch

A resource exists but does not match the requested type.

Fields

id: String

Resource identifier.

expected: &'static str

Expected kind.

actual: &'static str

Actual kind.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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<NulError> for Error

fn from(value: NulError) -> Self

Converts to this type from the input type.
