Trait Implementations

impl<'a> Clone for Query<'a>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Query<'a>

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

Formats the value using the given formatter.

impl<'a> From<Delete<'a>> for Query<'a>

fn from(delete: Delete<'a>) -> Self

Converts to this type from the input type.

impl<'a> From<Insert<'a>> for Query<'a>

fn from(insert: Insert<'a>) -> Self

Converts to this type from the input type.

impl<'a> From<MultiRowInsert<'a>> for Query<'a>

fn from(insert: MultiRowInsert<'a>) -> Query<'a>

Converts to this type from the input type.

impl<'a> From<Select<'a>> for Query<'a>

fn from(sel: Select<'a>) -> Query<'a>

Converts to this type from the input type.

impl<'a> From<SingleRowInsert<'a>> for Query<'a>

fn from(insert: SingleRowInsert<'a>) -> Query<'a>

Converts to this type from the input type.

impl<'a> From<Update<'a>> for Query<'a>

fn from(update: Update<'a>) -> Self

Converts to this type from the input type.

impl<'a> PartialEq for Query<'a>

fn eq(&self, other: &Query<'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.
