Enum StoreError 

pub enum StoreError {
    NotFound(String),
    InvalidScope(String),
    UnsupportedEdit {
        pid: String,
        kind: MemoryKind,
    },
    Database(DbErr),
    CacheInvariant(String),
}

Failure modes for crate::store::MemoryStore implementations.

Variants

NotFound(String)

InvalidScope(String)

UnsupportedEdit

edit was called on a memory whose kind does not support in-place edits. Today this is every non-Episodic kind; Semantic rows require the Override-conversion path that epic 0011 introduces, and editing them via this method would silently break the source_pid provenance contract.

Fields

pid: String

kind: MemoryKind

Database(DbErr)

CacheInvariant(String)

Trait Implementations

impl Debug for StoreError

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

Formats the value using the given formatter.

impl Display for StoreError

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

Formats the value using the given formatter.

impl Error for StoreError

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<DbErr> for StoreError

fn from(source: DbErr) -> Self

Converts to this type from the input type.

impl From<ScopeError> for StoreError

fn from(err: ScopeError) -> Self

Converts to this type from the input type.

impl From<StoreError> for ClientError

fn from(source: StoreError) -> Self

Converts to this type from the input type.
