Enum BitSpanError 

pub enum BitSpanError<T>
where
    T: BitStore,
{
    Null(NullPtrError),
    Misaligned(MisalignError<T>),
    TooLong(usize),
    TooHigh(*const T),
}

An error produced when creating BitSpan encoded references.

Variants

Null(NullPtrError)

A null pointer was provided.

Misaligned(MisalignError<T>)

The base element pointer is not aligned.

TooLong(usize)

The requested length exceeds the BitSpan length ceiling.

TooHigh(*const T)

The requested address is too high, and wraps to zero.

Trait Implementations

impl<T> Clone for BitSpanError<T>

where T: Clone + BitStore,

fn clone(&self) -> BitSpanError<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T> Debug for BitSpanError<T>

where T: BitStore,

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

Formats the value using the given formatter.

impl<T> Display for BitSpanError<T>

where T: BitStore,

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

Formats the value using the given formatter.

impl<T> Error for BitSpanError<T>

where T: BitStore,

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 #99301)

Provides type-based access to context intended for error reports.

impl<T> From<BitPtrError<T>> for BitSpanError<T>

where T: BitStore,

fn from(err: BitPtrError<T>) -> BitSpanError<T>

Converts to this type from the input type.

impl<T> From<MisalignError<T>> for BitSpanError<T>

where T: BitStore,

fn from(err: MisalignError<T>) -> BitSpanError<T>

Converts to this type from the input type.

impl<T> Hash for BitSpanError<T>

where T: Hash + BitStore,

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

where __H: Hasher,

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<T> Ord for BitSpanError<T>

where T: Ord + BitStore,

fn cmp(&self, other: &BitSpanError<T>) -> 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<T> PartialEq for BitSpanError<T>

where T: PartialEq + BitStore,

fn eq(&self, other: &BitSpanError<T>) -> 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<T> PartialOrd for BitSpanError<T>

where T: PartialOrd + BitStore,

fn partial_cmp(&self, other: &BitSpanError<T>) -> 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.
