Enum ToSqlOutput 

#[non_exhaustive]
pub enum ToSqlOutput<'a> {
    Borrowed(ValueRef<'a>),
    Owned(Value),
}

ToSqlOutput represents the possible output types for implementers of the ToSql trait.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Borrowed(ValueRef<'a>)

A borrowed SQLite-representable value.

Owned(Value)

An owned SQLite-representable value.

Trait Implementations

impl AsSqlTy for ToSqlOutput<'_>

const SQL_TY: SqlTy

The SQL type corresponding to this type.

type Borrowed<'p> = ToSqlOutput<'p>

The borrowed counterpart of this type (may be Self, e.g. for trivially-copiable types such as integers and floats). This is used e.g. for constructing the Table::PrimaryKey associated type, which in turn serves as the input type of helper queries such as SelectByKey and DeleteByKey.

fn format_check_constraint( column: &dyn Display, formatter: &mut Formatter<'_>, ) -> Result

If the domain of this type requires a CHECK constraint, this method should write out the relevant criteria. The column name will be given as the column argument. If the body of this function doesn’t write anything to the formatter, no CHECK constraint is going to be emitted.

impl<'a> Clone for ToSqlOutput<'a>

fn clone(&self) -> ToSqlOutput<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Param for ToSqlOutput<'_>

const PREFIX: ParamPrefix = ParamPrefix::Question

Primitives are bound as positional parameters, hence the prefix is ‘?’

fn bind(&self, statement: &mut Statement<'_>) -> Result<()>

Binds the primitive or the field(s) of a tuple to a raw rusqlite::Statement.

fn eq(&self, other: &ToSqlOutput<'a>) -> 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.

fn from_row(row: &Row<'_>) -> Result<Self>

Convert a dynamically-typed relational tuple to a statically-typed record.
