Enum SessionParameterValue 

pub enum SessionParameterValue {
    Scalar(Value),
    Table(Arc<BindingTable>),
}

Session-local query parameter value.

Scalar parameters are visible to statements as regular Values. Table parameters are registered in that statement’s binding-table registry and materialized as request-scoped TableRef values.

Variants

Scalar(Value)

Scalar query parameter value.

Table(Arc<BindingTable>)

Binding-table query parameter value.

Trait Implementations

impl Clone for SessionParameterValue

fn clone(&self) -> SessionParameterValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SessionParameterValue

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

Formats the value using the given formatter.

impl PartialEq for SessionParameterValue

fn eq(&self, other: &SessionParameterValue) -> 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.
