Trait OutcomeProjection 

pub trait OutcomeProjection<B, O>
where
    B: GatekeepSqlxBackend,
{
    // Required method
    fn constant(&self, outcome: &O) -> Result<SqlxFragment<B>, LowerError>;
}

Projection strategy for turning outcomes into SQL fragments.

Required Methods

fn constant(&self, outcome: &O) -> Result<SqlxFragment<B>, LowerError>

Builds a SQL fragment for a constant outcome.

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
