Enum DatabaseError

pub enum DatabaseError {
    FileNotFound,
    IOError(Error),
    InvalidGlobSet(Error),
    ChangeLogInUse,
    PoisonedLogMutex,
}

The primary error type for all database loading and mutation operations.

This enum consolidates errors from various sources, including file I/O, pattern matching, and concurrent access issues, into a single, unified type.

Variants

FileNotFound

An attempt was made to access a file that does not exist in the database.

IOError(Error)

An error occurred during a filesystem read or write operation.

InvalidGlobSet(Error)

The set of user-provided glob patterns could not be compiled into a GlobSet.

ChangeLogInUse

An attempt was made to commit or consume a ChangeLog while other references to it still exist, indicating that other threads may not have finished their work.

PoisonedLogMutex

The lock on a ChangeLog was “poisoned.”

This happens when a thread panics while holding the lock, leaving the data in an unrecoverable and potentially inconsistent state.

Trait Implementations

impl Debug for DatabaseError

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

Formats the value using the given formatter.

impl Display for DatabaseError

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

Formats the value using the given formatter.

impl Error for DatabaseError

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<Error> for DatabaseError

fn from(error: Error) -> Self

impl From<Error> for DatabaseError

fn from(error: GlobSetError) -> Self
