Enum TxError 

pub enum TxError {
    UnknownAttribute(EntityId),
    TypeMismatch(EntityId),
    LookupNotFound,
    LookupNotUnique,
    UniqueConflict,
    CasFailed,
    CasCardinality,
}

Transaction validation error.

Variants

UnknownAttribute(EntityId)

Attribute is absent from schema.

TypeMismatch(EntityId)

Value does not match attribute type.

LookupNotFound

A lookup ref did not resolve.

LookupNotUnique

Lookup refs require unique attributes.

UniqueConflict

A uniqueness constraint would be violated.

CasFailed

CAS old value did not match.

CasCardinality

CAS is only valid for cardinality one.

Trait Implementations

impl Debug for TxError

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

Formats the value using the given formatter.

impl Display for TxError

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

Formats the value using the given formatter.

impl Eq for TxError

impl Error for TxError

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 PartialEq for TxError

fn eq(&self, other: &TxError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
