Enum ResourceFetchError

pub enum ResourceFetchError {
    NotRegistered,
    DoesNotExist(ComponentId),
    NoResourceAccess(ComponentId),
}

An error that occurs when getting a resource of a given type in a world.

Variants

NotRegistered

The resource has never been initialized or registered with the world.

DoesNotExist(ComponentId)

The resource with the given ComponentId does not currently exist in the world.

NoResourceAccess(ComponentId)

Cannot get access to the resource with the given ComponentId in the world as it conflicts with an on going operation.

Trait Implementations

impl Clone for ResourceFetchError

fn clone(&self) -> ResourceFetchError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ResourceFetchError

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

Formats the value using the given formatter.

impl Display for ResourceFetchError

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

Formats the value using the given formatter.

impl Error for ResourceFetchError

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 ResourceFetchError

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