Enum AddError 

pub enum AddError {
    StaleId {
        id: u32,
        next: u32,
    },
}

Failure modes for NumberedValues::add. Upstream uses assert(ID >= NextUnusedID); we prefer a typed error so the parser’s diagnostic path can attribute the failure to a span.

Variants

StaleId

id is strictly less than the next-unused frontier — the slot is either already populated or skipped past. Mirrors the "Invalid value ID" assertion in NumberedValues.h.

Fields

id: u32

next: u32

Trait Implementations

impl Clone for AddError

fn clone(&self) -> AddError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AddError

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

Formats the value using the given formatter.

impl Display for AddError

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

Formats the value using the given formatter.

impl Eq for AddError

impl Error for AddError

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 Hash for AddError

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

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 PartialEq for AddError

fn eq(&self, other: &AddError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
