Trait DataFrameApplyArg 

pub trait DataFrameApplyArg {
    type Output;

    // Required method
    fn execute(
        self,
        frame: &DataFrame,
        axis: usize,
    ) -> Result<Self::Output, FrameError>;
}

Required Associated Types

type Output

Required Methods

fn execute( self, frame: &DataFrame, axis: usize, ) -> Result<Self::Output, FrameError>

Dyn Compatibility

This trait is dyn compatible.

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