Enum SectionViewError 

pub enum SectionViewError {
    ZeroSizedType,
    LengthNotMultipleOfSize {
        length: usize,
        elem_size: usize,
    },
    AlignmentMismatch {
        ptr_addr: usize,
        required: usize,
    },
}

Error returned when borrowing a section payload as a typed slice fails.

Performance

perf: unspecified; errors are returned only from typed-view paths.

Variants

ZeroSizedType

The requested element type is zero-sized, so it cannot tile a payload.

LengthNotMultipleOfSize

Payload byte length is not an exact multiple of size_of::<T>().

Fields

length: usize

Section payload length in bytes.

elem_size: usize

core::mem::size_of::<T>() for the requested element type.

AlignmentMismatch

Payload base address does not satisfy align_of::<T>().

Fields

ptr_addr: usize

Address of the payload’s first byte.

required: usize

core::mem::align_of::<T>() for the requested element type.

Trait Implementations

impl Clone for SectionViewError

fn clone(&self) -> SectionViewError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SectionViewError

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

Formats the value using the given formatter.

impl Display for SectionViewError

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

Formats the value using the given formatter.

impl Error for SectionViewError

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 SectionViewError

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