Variants

BadUuid(String)

PathAlreadyExists(String)

UnboundVariables(BTreeSet<String>)

InvalidArgumentName(String)

UnexpectedLostTransactRace

MissingCoreVocabulary(Keyword)

PreparedQuerySchemaMismatch

ValueTypeMismatch(ValueType, ValueType)

IoError(Error)

NotYetImplemented(String)

We’re just not done yet. Message that the feature is recognized but not yet implemented.

TransactionFunction(String)

Trait Implementations

impl Debug for MentatError

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

Formats the value using the given formatter.

impl Display for MentatError

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

Formats the value using the given formatter.

impl Error for MentatError

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
