Struct LVStatusCode

pub struct LVStatusCode(/* private fields */);

´LVStatusCode´ is a transparent newtype on i32 to represent all potential error codes and SUCCESS (0) as a success value.

This kind of status code corresponds to the Rust Result types. Therefore, it is named status and not error on purpose. There is no checks or guarantees if the code is a valid range or has an official labview definition.

Examples

use labview_interop::types::LVStatusCode;
let status = LVStatusCode::from(42);

assert_eq!(status, 42.into());

Implementations

impl LVStatusCode

pub fn description(&self) -> Cow<'static, str>

impl LVStatusCode

pub const SUCCESS: LVStatusCode

pub fn to_generic_result<T>(self, success_value: T) -> Result<T, LVInteropError>

this will convert the LVStatusCode to the generic LVError with no checks of validity

Trait Implementations

impl Clone for LVStatusCode

fn clone(&self) -> LVStatusCode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LVStatusCode

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

Formats the value using the given formatter.

impl Display for LVStatusCode

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

Formats the value using the given formatter.

impl Error for LVStatusCode

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<&InternalError> for LVStatusCode

fn from(err: &InternalError) -> LVStatusCode

Converts to this type from the input type.

impl From<&LVInteropError> for LVStatusCode

fn from(value: &LVInteropError) -> Self

Converts to this type from the input type.

impl From<&MgError> for LVStatusCode

fn from(errcode: &MgError) -> LVStatusCode

Converts to this type from the input type.

impl From<LVInteropError> for LVStatusCode

fn from(value: LVInteropError) -> Self

Converts to this type from the input type.

impl From<LVStatusCode> for LVInteropError

fn from(status: LVStatusCode) -> Self

Converts to this type from the input type.

impl From<LVStatusCode> for i32

fn from(code: LVStatusCode) -> i32

Converts to this type from the input type.

impl From<MgError> for LVStatusCode

fn from(errcode: MgError) -> LVStatusCode

Converts to this type from the input type.

impl<T> From<Result<T, LVInteropError>> for LVStatusCode

the conversion from LVInteropError back to LVStatusCode is important to return the status in extern “C” functions back to LV

fn from(value: Result<T>) -> Self

Converts to this type from the input type.

impl From<i32> for LVStatusCode

fn from(value: i32) -> LVStatusCode

Converts to this type from the input type.

impl PartialEq for LVStatusCode

fn eq(&self, other: &LVStatusCode) -> 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<LVStatusCode> for MgError

type Error = LVInteropError

The type returned in the event of a conversion error.

fn try_from(status: LVStatusCode) -> Result<Self, Self::Error>

Performs the conversion.

impl Copy for LVStatusCode

impl Eq for LVStatusCode

impl StructuralPartialEq for LVStatusCode
