Enum KernelConsoleReadError

#[repr(u64)]
pub enum KernelConsoleReadError {
    Unknown = 0,
    WouldBlock = 1,
    NoSuchDevice = 2,
    IOError = 3,
}

Possible errors returned by reading from the kernel console’s input.

Variants

Unknown = 0

Unknown error.

WouldBlock = 1

Operation would block, but non-blocking was requested.

NoSuchDevice = 2

Failed to read because there was no input mechanism made available to the kernel.

IOError = 3

The input mechanism had an internal error.

Trait Implementations

impl Clone for KernelConsoleReadError

fn clone(&self) -> KernelConsoleReadError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for KernelConsoleReadError

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

Formats the value using the given formatter.

impl Display for KernelConsoleReadError

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

Formats the value using the given formatter.

impl Error for KernelConsoleReadError

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<KernelConsoleReadError> for u64

fn from(enum_value: KernelConsoleReadError) -> Self

Converts to this type from the input type.

impl From<u64> for KernelConsoleReadError

fn from(number: u64) -> Self

Converts to this type from the input type.

impl FromPrimitive for KernelConsoleReadError

type Primitive = u64

fn from_primitive(number: Self::Primitive) -> Self

impl Hash for KernelConsoleReadError

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for KernelConsoleReadError

fn cmp(&self, other: &KernelConsoleReadError) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for KernelConsoleReadError

fn eq(&self, other: &KernelConsoleReadError) -> 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 PartialOrd for KernelConsoleReadError

fn partial_cmp(&self, other: &KernelConsoleReadError) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
