Trait PartitionExpressions 

pub trait PartitionExpressions {
    // Required methods
    fn evaluate_bound(
        &self,
        expression: &Expr,
        params: &[SQLParam],
    ) -> Result<Value, SQLError>;
    fn evaluate_row(
        &self,
        expression: &Expr,
        row: &ResultRow,
        schema: &RowSchema,
        params: &[SQLParam],
    ) -> Result<Value, SQLError>;
}

Evaluate declared partition keys and bounds with the caller’s expression scope.

Required Methods

fn evaluate_bound( &self, expression: &Expr, params: &[SQLParam], ) -> Result<Value, SQLError>

fn evaluate_row( &self, expression: &Expr, row: &ResultRow, schema: &RowSchema, params: &[SQLParam], ) -> Result<Value, SQLError>

Dyn Compatibility

This trait is dyn compatible.

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