Implementations

impl<T> Column<T>

pub const fn field(&self) -> &'static str

pub const fn sql(&self) -> &'static str

Trait Implementations

impl<T> Clone for Column<T>

where T: Table,

fn clone(&self) -> Column<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T> Debug for Column<T>

where T: Debug + Table,

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

Formats the value using the given formatter.

impl<T> PartialEq for Column<T>

where T: PartialEq + Table,

fn eq(&self, other: &Column<T>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<T> Copy for Column<T>

where T: Copy + Table,

impl<T> Eq for Column<T>

where T: Eq + Table,

impl<T> StructuralEq for Column<T>

where T: Table,

impl<T> StructuralPartialEq for Column<T>

where T: Table,
