Enum SectionBindError 

pub enum SectionBindError {
    Missing {
        kind: u32,
    },
    VersionMismatch {
        kind: u32,
        expected: u32,

    View {

        error: SectionViewError,
    },
}

Error returned when binding a width-typed section by kind and version.

Returned by Snapshot::typed_section: a single error covering the lookup, version check, and typed-view steps that every layout crate previously open-coded with its own variants.

Performance

perf: unspecified; errors are returned only from section-binding paths.

Variants

Missing

No section with the requested kind was present.

Fields

kind: u32

Requested section kind.

VersionMismatch

The section was present but its version did not match.

Fields

kind: u32

Requested section kind.

expected: u32

Version the caller required.

actual: u32

Version recorded in the section entry.

View

The payload could not be borrowed as the requested little-endian word.

Fields

kind: u32

Requested section kind.

error: SectionViewError

Underlying typed-view failure.

Trait Implementations

impl Clone for SectionBindError

fn clone(&self) -> SectionBindError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for SectionBindError

impl Debug for SectionBindError

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

Formats the value using the given formatter.

impl Display for SectionBindError

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

Formats the value using the given formatter.

impl Eq for SectionBindError

impl Error for SectionBindError

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 SectionBindError

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