        errno: i32,

Error returned when reading an nvpair value fails.

Variants

ValueReadFailed

A nvpair_value_* C function returned a non-zero error code.

Fields

pair_name: String

type_code: data_type_t

errno: i32

NullPointer

A C function returned a null pointer where a valid one was required.

Fields

pair_name: String

type_code: data_type_t

NullName

nvpair_name returned a null pointer for a pair.

Trait Implementations

impl Clone for NvError

fn clone(&self) -> NvError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NvError

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

Formats the value using the given formatter.

impl Display for NvError

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

Formats the value using the given formatter.

impl Error for NvError

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 PartialEq for NvError

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