Enum Error 

pub enum Error {
    Ul(UlError),
    DeviceCreateFailed,
    InvalidArgument(&'static str),
    Internal(&'static str),
}

Errors that can occur when interacting with the uldaq library.

Variants

Ul(UlError)

An error code returned by the UL library itself.

DeviceCreateFailed

DaqDevice::create returned a null handle without a specific error code. This typically means the device is already in use, or the descriptor is invalid.

InvalidArgument(&'static str)

An invalid argument was passed to a function.

Internal(&'static str)

An internal invariant was violated; this is probably a bug.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

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 Eq for Error

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<UlError> for Error

fn from(e: UlError) -> Error

Converts to this type from the input type.

impl PartialEq for Error

fn eq(&self, other: &Error) -> bool

Equality operator ==.

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

Inequality operator !=.
