Filter

scirs2_datasets::streaming::transforms

Struct Filter 

Source 
pub struct Filter { /* private fields */ }
Expand description

Row-level filter: keeps only rows for which condition(&row) == true.

Implementations§

Source§

impl Filter

Source

pub fn new(f: impl Fn(&[f64]) -> bool + Send + Sync + 'static) -> Self

Create a filter from an arbitrary predicate on a row’s feature slice.

Trait Implementations§

Source§

impl Transform for Filter

Source§

fn apply( &self, chunk: StreamingDataChunk, ) -> Result<StreamingDataChunk, DatasetsError>

Apply the transformation to chunk, returning a (potentially new) chunk. Implementations may mutate in place and return the same chunk, or allocate a new one.
