Enum StoreError 

#[non_exhaustive]
pub enum StoreError {
    Io(Error),
    Serialization(Box<dyn Error + Send + Sync>),
    Validation(String),
    Connection(Box<dyn Error + Send + Sync>),
    Database(Box<dyn Error + Send + Sync>),
    RetriesExhausted {
        op: String,
    },
    Migration(Box<dyn Error + Send + Sync>),
    InvalidConfig(String),
    DeviceNotFound(i32),
}

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.

Io(Error)

Serialization(Box<dyn Error + Send + Sync>)

Validation(String)

Validation failure with a descriptive message and no underlying typed source — e.g. “Invalid foo length: 17”. Prefer Serialization or a dedicated typed variant if a real source exists.

Connection(Box<dyn Error + Send + Sync>)

Database(Box<dyn Error + Send + Sync>)

RetriesExhausted

Fields

op: String

Migration(Box<dyn Error + Send + Sync>)

InvalidConfig(String)

DeviceNotFound(i32)

Implementations

impl StoreError

pub fn is_database_busy_or_locked(&self) -> bool

Walks the error source chain and returns true if any layer’s Display indicates a SQLite busy/locked condition. Used by retry layers that can’t depend on a specific backend (Diesel, libsql, etc.) directly.

Substring matching is necessary because SQLite reports BUSY/LOCKED through sqlite3_errmsg() strings; the error code itself is mapped to Diesel::DatabaseError(Unknown, _) (or similar) without further discrimination.

Trait Implementations

impl Debug for StoreError

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

Formats the value using the given formatter.

impl Display for StoreError

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

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.
