Enum SQLiteInsertValue 

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

One field of a generated insert model: left out, NULL, or a value.

You rarely build this directly. The with_* setters and new on a generated InsertX model convert their arguments into it.

Variants

Omit

Leave the column out of the INSERT so the database default applies.

Null

Insert NULL.

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

Insert a bound value, placeholder or SQL expression.

Implementations

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

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

Converts this field to a 'static form that owns its data.

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: Clone + SQLParam, T: Clone> Clone for SQLiteInsertValue<'a, V, T>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a, V: Debug + SQLParam, T: Debug> Debug for SQLiteInsertValue<'a, V, T>

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

Formats the value using the given formatter.

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

fn default() -> Self

Returns the “default value” for a type.

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

fn from(placeholder: Placeholder) -> Self

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) -> Self

Converts to this type from the input type.

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

fn from(typed: TypedPlaceholder<M, N>) -> Self

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]) -> Self

Converts to this type from the input type.
