Trait butane_core::DataResult

pub trait DataResult: Sized {
    type DBO: DataObject;

    const COLUMNS: &'static [Column];

    fn from_row<'a>(row: &(dyn BackendRow + 'a)) -> Result<Self>
    where
        Self: Sized;
    fn query() -> Query<Self>;
}

A type which may be the result of a database query.

Every result type must have a corresponding object type and the columns of the result type must be a subset of the columns of the object type. The purpose of a result type which is not also an object type is to allow a query to retrieve a subset of an object’s columns.

Associated Types

type DBO: DataObject

Corresponding object type.

Associated Constants

const COLUMNS: &'static [Column]

Required methods

fn from_row<'a>(row: &(dyn BackendRow + 'a)) -> Result<Self> where
    Self: Sized, 

fn query() -> Query<Self>

Create a blank query (matching all rows) for this type.
