Struct Column 

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

A typed column reference: M is the model, T the field type.

#[derive(Model)] generates one per field (User::EMAIL), so filters check both the column name and the value type at compile time.

Implementations

impl<M, T> Column<M, T>

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

Used by #[derive(Model)]; you rarely call it directly.

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

Returns the column name.

pub const fn asc(self) -> Ordering<M>

Returns an ascending ordering for this column.

pub const fn desc(self) -> Ordering<M>

Returns a descending ordering for this column.
