Trait ToDataFrame 

pub trait ToDataFrame {
    // Required methods
    fn to_dataframe(&self) -> Result<DataFrame, PolarsError>;
    fn empty_dataframe() -> Result<DataFrame, PolarsError>;
    fn schema() -> Result<Vec<(String, DataType)>, PolarsError>;
}

Required Methods

fn to_dataframe(&self) -> Result<DataFrame, PolarsError>

Errors

Returns an error if DataFrame construction fails.

fn empty_dataframe() -> Result<DataFrame, PolarsError>

Errors

Returns an error if DataFrame construction fails.

fn schema() -> Result<Vec<(String, DataType)>, PolarsError>

Errors

Returns an error if schema generation fails.

Dyn Compatibility

This trait is not dyn compatible.

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