Struct IncompatibleVecTargetError

pub struct IncompatibleVecTargetError<S, T> {
    pub vec: Vec<S>,
    /* private fields */
}

Incompatible vector transmutation error.

Returned when the element type S does not allow a safe vector transmutation to the target element type T. This happens when either the size or minimum memory alignment requirements are not met:

• std::mem::align_of::<S>() != std::mem::align_of::<T>()
• std::mem::size_of::<S>() != std::mem::size_of::<T>()

Fields

vec: Vec<S>

The original vector.

Implementations

impl<S, T> IncompatibleVecTargetError<S, T>

pub fn new(vec: Vec<S>) -> Self

Create an error with the given vector.

pub unsafe fn copy_unchecked(&self) -> Vec<T>

Create a copy of the data, transmuted into a new vector. As the vector will be properly aligned for accessing values of type T, this operation will not fail due to memory alignment constraints.

Safety

The byte data in the vector needs to correspond to a valid contiguous sequence of T values.

pub fn copy(&self) -> Vec<T>

where T: TriviallyTransmutable,

Create a copy of the data, transmuted into a new vector. As T is trivially transmutable, and the new vector will be properly allocated for accessing values of type T, this operation is safe and will never fail.

Trait Implementations

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

🔬This is a nightly-only experimental API. (error_generic_member_access)

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

impl<S: PartialEq, T: PartialEq> PartialEq for IncompatibleVecTargetError<S, T>

fn eq(&self, other: &IncompatibleVecTargetError<S, 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.
