Trait CrossJoinFilter 

pub trait CrossJoinFilter: Send + Sync {
    // Required method
    fn evaluate(&self, df: &DataFrame) -> PolarsResult<BooleanChunked>;

    // Provided method
    fn apply(&self, df: DataFrame) -> PolarsResult<DataFrame> { ... }
}

Required Methods

fn evaluate(&self, df: &DataFrame) -> PolarsResult<BooleanChunked>

Evaluates the filter predicate on df, returning a boolean mask.

Provided Methods

fn apply(&self, df: DataFrame) -> PolarsResult<DataFrame>

Dyn Compatibility

This trait is dyn compatible.

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