Struct Column 

pub struct Column<A, T> { /* private fields */ }

Implementations

impl<A, T> Column<A, T>

pub const fn new(field: &'static str) -> Self

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

impl<A: Aggregate, T: Cast> Column<A, T>

pub fn eq(self, value: T) -> Condition<A>

None matches the rows where the value is null.

pub fn ne(self, value: T) -> Condition<A>

Also matches the rows holding a null where value does not, as a nullable value’s.

pub fn in_(self, values: impl IntoIterator<Item = T>) -> Condition<A>

An empty list matches nothing; a value holding a null matches as in eq.

pub fn like(self, pattern: &str) -> Condition<A>

pub fn asc(self) -> Sort<A>

pub fn desc(self) -> Sort<A>

impl<A: Aggregate, T: Ordered> Column<A, T>

Of a nullable value, a null row never matches: give is_null its own condition to keep them.

pub fn gt(self, value: impl Into<T>) -> Condition<A>

pub fn gte(self, value: impl Into<T>) -> Condition<A>

pub fn lt(self, value: impl Into<T>) -> Condition<A>

pub fn lte(self, value: impl Into<T>) -> Condition<A>

pub fn between(self, low: impl Into<T>, high: impl Into<T>) -> Condition<A>

Both ends included.

impl<A: Aggregate, T: Cast> Column<A, Option<T>>

pub fn is_null(self) -> Condition<A>

pub fn is_not_null(self) -> Condition<A>
