Trait ToDataFrameTrait 

pub trait ToDataFrameTrait {
    // 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", so this trait is not object safe.
