Struct TidyFrame 

pub struct TidyFrame { /* private fields */ }

A materialized, mutable DataFrame with copy-on-write alias safety.

Wraps Rc<RefCell<DataFrame>>. Cloning a TidyFrame shares the buffer; writing through mutate() triggers a deep copy if the refcount > 1, ensuring other views are not corrupted.

Implementations

impl TidyFrame

pub fn from_df(df: DataFrame) -> Self

Wrap an existing DataFrame.

pub fn borrow(&self) -> Ref<'_, DataFrame>

Get a shared view of the inner DataFrame.

pub fn view(&self) -> TidyView

Apply further tidy operations on this frame.

pub fn mutate(&mut self, assignments: &[(&str, DExpr)]) -> Result<(), TidyError>

Alias-safe mutate: if this TidyFrame is shared, clones first.

Trait Implementations

impl Clone for TidyFrame

fn clone(&self) -> TidyFrame

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TidyFrame

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
