pub trait IntoDataFrameSplit: Sized {
// Required method
fn into_dataframe_split(self) -> List;
}Expand description
Enum rows → variant-partitioned R data.frames. The split-representation
sibling of IntoDataFrame.
Where IntoDataFrame produces one aligned data.frame (field-name
union, NA fill for columns a variant doesn’t carry), this verb partitions
the rows by variant: each partition is a data.frame with only that
variant’s own columns (non-optional types — no NA fill from sibling
variants), keyed by the snake_case variant name.
Implemented by #[derive(DataFrameRow)] on an enum row type (for
Vec<Row>, via the hidden DataFrameRowSplit bridge below). Struct rows
have no variants to partition, so the struct derive does not provide it.
Call it on your data: rows.into_dataframe_split().
§Return shape
The returned List is a bare data.frame for a single-variant enum and a
named R list of data.frames (one per variant) otherwise. Variants absent
from the input still appear as 0-row data.frames with that variant’s
column shape; unit variants produce a 0-column data.frame with the
correct row count. List is IntoR, so a #[miniextendr] function
returns it directly.
Required Methods§
Sourcefn into_dataframe_split(self) -> List
fn into_dataframe_split(self) -> List
Partition the rows by variant into one data.frame per variant.
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety".
