Enum NatRangeIndexError 

pub enum NatRangeIndexError {
    Empty,
    DoesNotFitUsize {
        size: u64,
    },
}

Error returned when an AST/runtime Nat range size cannot become a concrete index.

Variants

Empty

Empty Nat ranges are deliberately not representable.

DoesNotFitUsize

The source-level u64 size does not fit in this target’s in-memory index size.

Fields

size: u64

Trait Implementations

impl Clone for NatRangeIndexError

fn clone(&self) -> NatRangeIndexError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for NatRangeIndexError

impl Debug for NatRangeIndexError

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

Formats the value using the given formatter.

impl Display for NatRangeIndexError

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

Formats the value using the given formatter.

impl Eq for NatRangeIndexError

impl Error for NatRangeIndexError

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 NatRangeIndexError

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