Enum MySQLInsertValue 

pub enum MySQLInsertValue<'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 SQL NULL.

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

Insert a value, placeholder, or typed SQL expression.

Implementations

impl<'a, T> MySQLInsertValue<'a, MySQLValue<'a>, T>

pub fn into_owned(self) -> MySQLInsertValue<'static, MySQLValue<'static>, T>

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