Enum AvailabilityScopeError 

pub enum AvailabilityScopeError {
    UnknownWarehouse(Uuid),
    GroupPivot(Uuid),
    EmptyItemSet,
    DuplicateItem(Uuid),
    NegativeHeld(Uuid),
    Unwired(&'static str),
    Database(Error),
}

The availability scope read’s typed refusals.

Variants

UnknownWarehouse(Uuid)

The pivot warehouse does not exist or is soft-deleted under the ambient org scope. Carries the warehouse id.

GroupPivot(Uuid)

The pivot warehouse is a grouping node, not a concrete stock warehouse. Carries the warehouse id.

EmptyItemSet

The item set (or demand list) is empty — a vacuous read that would answer “sold out” over nothing.

DuplicateItem(Uuid)

The same item appears twice in one request. The caller must sum its own per-item quantities before asking.

NegativeHeld(Uuid)

A demand carries a negative held quantity.

Unwired(&'static str)

The port has no adapter wired in this composition — the fail-loud default. No availability number is fabricated, so no surface can render a guessed stock state.

Database(Error)

The database transport.

Trait Implementations

impl Debug for AvailabilityScopeError

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

Formats the value using the given formatter.

impl Display for AvailabilityScopeError

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

Formats the value using the given formatter.

impl Error for AvailabilityScopeError

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 From<Error> for AvailabilityScopeError

fn from(source: Error) -> Self

Converts to this type from the input type.
