Enum StateStoreError 

pub enum StateStoreError {
    Substrate(String),
    Serialization(String),
}

Substrate-level state-store failure.

Distinct from “state not found” (which is Ok(None) from take). Indicates the substrate itself is unhealthy (network, auth, serialization, etc.). Surfaces as [super::StartError::StateStore] or [super::CallbackError::StateStore] depending on which side hit it.

Variants

Substrate(String)

Serialization(String)

Trait Implementations

impl Debug for StateStoreError

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

Formats the value using the given formatter.

impl Display for StateStoreError

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

Formats the value using the given formatter.

impl Error for StateStoreError

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>)
