Enum BookingError 

pub enum BookingError {
    Inventory(AccountedBookingError),
    Interpolation(InterpolationError),
}

Errors that can occur during booking.

Inventory-level failures (insufficient units, no matching lot, ambiguous match, currency mismatch) are unified under BookingError::Inventory, which carries an AccountedBookingError from rustledger-core. This keeps the user-facing wording in one place so it cannot drift between the booking layer and the validator — see #748 / #750.

Variants

Inventory(AccountedBookingError)

An inventory-level booking failure (insufficient units, no matching lot, ambiguous match, currency mismatch).

Display is delegated to the inner AccountedBookingError, which is the single canonical source of wording for booking errors. The pta-standards reduction-exceeds-inventory conformance test depends on this Display containing the literal substring "not enough".

Interpolation(InterpolationError)

Interpolation failed after booking.

Trait Implementations

impl Clone for BookingError

fn clone(&self) -> BookingError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BookingError

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

Formats the value using the given formatter.

impl Display for BookingError

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

Formats the value using the given formatter.

impl Error for BookingError

fn source(&self) -> Option<&(dyn Error + 'static)>

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<InterpolationError> for BookingError

fn from(source: InterpolationError) -> Self

Converts to this type from the input type.
