pub enum AriaError {
    NoItems,
    NoEligibleItems,
    UserNotFound(String),
    ItemNotFound(String),
    CyclicPrerequisite(String),
    NoFactors,

}

Variants

NoItems

No items registered in the engine

NoEligibleItems

All items filtered out (prereqs, already seen, etc.)

UserNotFound(String)

User ID not found

ItemNotFound(String)

Trait Implementations

impl Debug for AriaError

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

Formats the value using the given formatter.

impl Display for AriaError

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

Formats the value using the given formatter.

impl Error for AriaError

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 AriaError

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