Enum SQLiteInsertValue 

pub enum SQLiteInsertValue<'a, V, T>
where
    V: SQLParam,
{
    Omit,
    Null,
    Value(ValueWrapper<'a, V, T>),
}

Available on crate feature sqlite only.

Represents a value for INSERT operations that can be omitted, null, or a SQL expression

Variants

Omit

Omit this column from the INSERT (use database default)

Null

Explicitly insert NULL

Value(ValueWrapper<'a, V, T>)

Insert a SQL expression (value, placeholder, etc.)

Implementations

impl<'a, T> SQLiteInsertValue<'a, SQLiteValue<'a>, T>

pub fn into_owned(self) -> SQLiteInsertValue<'static, SQLiteValue<'static>, T>

Converts this InsertValue to an owned version with ’static lifetime.

The whole SQL fragment is kept: placeholders stay unbound and expressions such as json(?) keep their shape, with every bound value detached from its borrow.

Trait Implementations

impl<'a, V, T> Clone for SQLiteInsertValue<'a, V, T>

where V: Clone + SQLParam, T: Clone,

fn clone(&self) -> SQLiteInsertValue<'a, V, T>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a, V, T> Debug for SQLiteInsertValue<'a, V, T>

where V: Debug + SQLParam, T: Debug,

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

Formats the value using the given formatter.

impl<'a, V, T> Default for SQLiteInsertValue<'a, V, T>

where V: SQLParam,

fn default() -> SQLiteInsertValue<'a, V, T>

Returns the “default value” for a type.

impl<'a, T> From<Placeholder> for SQLiteInsertValue<'a, SQLiteValue<'a>, T>

fn from(placeholder: Placeholder) -> SQLiteInsertValue<'a, SQLiteValue<'a>, T>

Converts to this type from the input type.

impl<'a, T, U> From<T> for SQLiteInsertValue<'a, SQLiteValue<'a>, U>

where T: TryInto<SQLiteValue<'a>> + TryInto<U>, U: TryInto<SQLiteValue<'a>>,

Converts a setter argument to the column’s type, then to a bound value.

Panics

Panics when the argument does not fit the column type (an integer out of range, a JSON payload that fails to serialize), rather than storing NULL in its place.

fn from(value: T) -> SQLiteInsertValue<'a, SQLiteValue<'a>, U>

Converts to this type from the input type.

impl<'a, M, N, T> From<TypedPlaceholder<M, N>> for SQLiteInsertValue<'a, SQLiteValue<'a>, T>

where M: DataType, N: Nullability,

fn from( typed: TypedPlaceholder<M, N>, ) -> SQLiteInsertValue<'a, SQLiteValue<'a>, T>

Converts to this type from the input type.

impl<'a, const N: usize> From<[u8; N]> for SQLiteInsertValue<'a, SQLiteValue<'a>, Vec<u8>>

fn from(value: [u8; N]) -> SQLiteInsertValue<'a, SQLiteValue<'a>, Vec<u8>>

Converts to this type from the input type.

impl<V, T> JsonColumnOperand for SQLiteInsertValue<'_, V, T>

where V: SQLParam,

impl<'a, T> JsonColumnValue<T> for SQLiteInsertValue<'a, SQLiteValue<'a>, T>

where T: Serialize,

fn from_json(value: Json<T>) -> SQLiteInsertValue<'a, SQLiteValue<'a>, T>

Converts value into the SQL value of a JSON column.
