Method sort

datafusion/core/src/dataframe/mod.rs:1224–1231

Sort the DataFrame by the specified sorting expressions. Note that any expression can be turned into a sort expression by calling its [sort](Expr::sort) method. # Example ``` # use datafusion::prelude::*; # use datafusion::error::Result; # use datafusion_common::assert_batches_sorted_eq; # #[tokio::main] # async fn main() -> Result<()> { let ctx = SessionContext::new(); let df = ctx .read_csv("

(self, expr: Vec<SortExpr>)

    /// # }
    /// ```
    pub fn sort(self, expr: Vec<SortExpr>) -> Result<DataFrame> {
        let plan = LogicalPlanBuilder::from(self.plan).sort(expr)?.build()?;
        Ok(DataFrame {
            session_state: self.session_state,
            plan,
            projection_requires_validation: self.projection_requires_validation,
        })
    }

    /// Join this `DataFrame` with another `DataFrame` using explicitly specified
    /// columns and an optional filter expression.
