Module extendr_api::prelude::col

Column vector type.

Structs

• Col
  Heap allocated resizable column vector.
• ColMut
  Mutable view over a column vector, similar to a mutable reference to a strided slice.
• ColRef
  Immutable view over a column vector, similar to an immutable reference to a strided slice.

Traits

• AsColMut
  Trait for types that can be converted to a mutable column view.
• AsColRef
  Trait for types that can be converted to a column view.
• ColBatch
  Type that can be interpreted as a batch of column vectors. Can be a single column or a matrix.
• ColBatchMut
  Type that can be interpreted as a mutable batch of column vectors. Can be a single column or a matrix.
• ColIndex
  Represents a type that can be used to slice a column, such as an index or a range of indices.

Functions

• from_mut
  Returns a view over a column with 1 row containing value as its only element, pointing to value.
• from_mut_generic
  Returns a view over a column with 1 row containing value as its only element, pointing to value.
• from_raw_parts^⚠
  Creates a ColRef from pointers to the column vector data, number of rows, and row stride.
• from_raw_parts_mut^⚠
  Creates a ColMut from pointers to the column vector data, number of rows, and row stride.
• from_ref
  Returns a view over a column with 1 row containing value as its only element, pointing to value.
• from_ref_generic
  Returns a view over a column with 1 row containing value as its only element, pointing to value.
• from_repeated_ref
  Returns a view over a column with nrows rows containing value repeated for all elements.
• from_repeated_ref_generic
  Returns a view over a column with nrows rows containing value repeated for all elements.
• from_slice
  Creates a ColRef from slice views over the column vector data, The result has the same number of rows as the length of the input slice.
• from_slice_generic
  Creates a ColRef from slice views over the column vector data, The result has the same number of rows as the length of the input slice.
• from_slice_mut
  Creates a ColMut from slice views over the column vector data, The result has the same number of rows as the length of the input slice.
• from_slice_mut_generic
  Creates a ColMut from slice views over the column vector data, The result has the same number of rows as the length of the input slice.
