Struct Records 

pub struct Records(Vec<(&'static str, Column)>);

A column-oriented record set: stable names, parallel columns of equal length.

The conversion into a dataframe or a CSV deliberately does not live here. It lives in the Python package behind a function-local import, so no crate in this workspace depends on a dataframe library and the Python dependency stays genuinely optional. The text rendering does live here, as Display, so a Rust caller and a Python print show one table.

The readings are the Python table’s: columns in producer order, column by name, records["name"] panicking with the held names for one it does not hold, len as the row count, and the typed readings on each Column.

Implementations

impl Records

pub fn new(columns: Vec<(&'static str, Column)>) -> Self

A table from its named columns, in producer order.

pub fn columns(&self) -> impl Iterator<Item = &'static str> + '_

The column names, in producer order.

pub fn column(&self, name: &str) -> Option<&Column>

The column under name, or None for a name the table does not hold.

pub fn len(&self) -> usize

How many rows the table holds — the length of every column.

pub fn is_empty(&self) -> bool

Whether the table holds no rows.

pub fn iter(&self) -> Iter<'_, (&'static str, Column)>

The (name, column) pairs, in producer order.

Trait Implementations

impl Clone for Records

fn clone(&self) -> Records

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Records

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

Formats the value using the given formatter.

impl Display for Records

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

The table as text: a header line, a rule of ─ with ┼ at each join, and one line per row with cells separated by │, each padded by a space. What print(records) shows in Python.

impl From<Vec<(&'static str, Column)>> for Records

fn from(columns: Vec<(&'static str, Column)>) -> Self

Converts to this type from the input type.

impl Index<&str> for Records

fn index(&self, name: &str) -> &Column

The column under name.

Panics

For a name the table does not hold, naming the held columns — the Python table’s KeyError.

type Output = Column

The returned type after indexing.

impl<'a> IntoIterator for &'a Records

type Item = &'a (&'static str, Column)

The type of the elements being iterated over.

type IntoIter = Iter<'a, (&'static str, Column)>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl IntoIterator for Records

type Item = (&'static str, Column)

The type of the elements being iterated over.

type IntoIter = IntoIter<(&'static str, Column)>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl PartialEq for Records

fn eq(&self, other: &Records) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
