Enum StartQueryError 

#[non_exhaustive]
pub enum StartQueryError {
    StorageFull(StorageFullError),
}

Errors raised by Endpoint::try_start_query.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

StorageFull(StorageFullError)

The internal routing pool is full.

Implementations

impl StartQueryError

pub const fn is_storage_full(&self) -> bool

Returns true if this value is of type StorageFull. Returns false otherwise

impl StartQueryError

pub fn unwrap_storage_full(self) -> StorageFullError

Unwraps this value to the StartQueryError::StorageFull variant. Panics if this value is of any other type.

pub fn unwrap_storage_full_ref(&self) -> &StorageFullError

Unwraps this reference to the StartQueryError::StorageFull variant. Panics if this value is of any other type.

impl StartQueryError

pub fn try_unwrap_storage_full( self, ) -> Result<StorageFullError, TryUnwrapError<Self>>

Attempts to unwrap this value to the StartQueryError::StorageFull variant. Returns a [TryUnwrapError] with the original value if this value is of any other type.

pub fn try_unwrap_storage_full_ref( &self, ) -> Result<&StorageFullError, TryUnwrapError<&Self>>

Attempts to unwrap this reference to the StartQueryError::StorageFull variant. Returns a [TryUnwrapError] with the original value if this value is of any other type.

Trait Implementations

impl Clone for StartQueryError

fn clone(&self) -> StartQueryError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StartQueryError

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

Formats the value using the given formatter.

impl Display for StartQueryError

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

Formats the value using the given formatter.

impl Error for StartQueryError

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<StorageFullError> for StartQueryError

fn from(source: StorageFullError) -> Self

Converts to this type from the input type.
