Variants

SqliteError(Error)

Wrapper around rusqlite::Error.

ConditionTypeNotFound(String)

Requested condition name does not exist.

MissingSchemaVersion

The SQLite file does not contain the expected schema version entry.

EmptyConditionList

Fetch API requires at least one condition name.

PathResolutionError(Error)

Failed to resolve or canonicalize a filesystem path.

GlueXCoreError(GlueXCoreError)

Timestamp parsing failed while decoding a time condition.

UnknownValueType(String)

Encountered a value type identifier we do not understand.

ConditionTypeMismatch

Predicate requested a condition with a mismatched type.

Fields

condition_name: String

Name of the offending condition.

expected: ValueType

Type requested by the predicate builder.

actual: ValueType

Type stored in the database schema.

MissingTimeValue

time condition row was missing a time_value entry.

Fields

condition_name: String

Name of the time-valued condition.

run_number: RunNumber

Run number missing the time value.

MissingConnectionEnv(String)

Required environment variable is not set.

Trait Implementations

impl Debug for RCDBError

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

Formats the value using the given formatter.

impl Display for RCDBError

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

Formats the value using the given formatter.

impl Error for RCDBError

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 RCDBError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for RCDBError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<GlueXCoreError> for RCDBError

fn from(source: GlueXCoreError) -> Self

Converts to this type from the input type.
