    pub cols: Vec<Box<str>>,
    pub value: AlgebraicValue,
}

Fields

constraint_name: Box<str>

table_name: Box<str>

cols: Vec<Box<str>>

value: AlgebraicValue

Implementations

impl UniqueConstraintViolation

pub fn build_with_index_schema( schema: &TableSchema, index: &TableIndex, index_schema: &IndexSchema, value: AlgebraicValue, ) -> Self

Returns a unique constraint violation error for the given index and the value that would have been duplicated.

In this version, the index_schema is explicitly passed.

Trait Implementations

impl Debug for UniqueConstraintViolation

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

Formats the value using the given formatter.

impl Display for UniqueConstraintViolation

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

Formats the value using the given formatter.

impl Error for UniqueConstraintViolation

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<UniqueConstraintViolation> for InsertError

fn from(source: UniqueConstraintViolation) -> Self

Converts to this type from the input type.

impl PartialEq for UniqueConstraintViolation

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
