Enum IsamError 

pub enum IsamError {
    Io(Error),
    Bincode(Box<ErrorKind>),
    KeyNotFound,
    DuplicateKey,
    CorruptIndex(String),
    LockPoisoned,
}

Variants

Io(Error)

Wraps any std::io::Error (e.g. file not found, permission denied). The #[from] attribute lets the ? operator convert io::Error automatically — no explicit .map_err(...) needed.

Bincode(Box<ErrorKind>)

Wraps bincode serialization/deserialization errors.

KeyNotFound

The requested key does not exist (used for update on missing key).

DuplicateKey

Attempted to insert a key that already exists in the index.

CorruptIndex(String)

The index file is corrupt or was created by an incompatible version.

LockPoisoned

A thread panicked while holding the database lock.

Trait Implementations

impl Debug for IsamError

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

Formats the value using the given formatter.

impl Display for IsamError

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

Formats the value using the given formatter.

impl Error for IsamError

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<Box<ErrorKind>> for IsamError

fn from(source: Box<ErrorKind>) -> Self

Converts to this type from the input type.

impl From<Error> for IsamError

fn from(source: Error) -> Self
