Struct Data 

pub struct Data(/* private fields */);

Columns by name, each len rows long. Cloning is one reference count.

Every change takes a generation no other table has had, and a clone shares its original’s, so equal generations mean equal contents. A table rebuilt from the same values is a new generation: hold the table, not the values it was built from, to keep what was computed from it.

Implementations

impl Data

pub fn new() -> Self

pub fn with(self, field: impl Into<SharedString>, column: Column) -> Self

Adds field, or replaces the column of that name in place.

Panics

If the table already has a column and column is not as long.

pub fn number( self, field: impl Into<SharedString>, values: impl Into<Arc<[f64]>>, ) -> Self

pub fn text<S: Into<SharedString>>( self, field: impl Into<SharedString>, values: impl IntoIterator<Item = S>, ) -> Self

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

pub fn fields(&self) -> impl Iterator<Item = (&SharedString, &Column)>

In the order they were first added.

pub fn len(&self) -> usize

Rows. 0 for a table with no columns.

pub fn is_empty(&self) -> bool

pub fn generation(&self) -> u64

0 for a table with no columns.

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

Performs copy-assignment from source.

impl Debug for Data

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

impl Default for Data

fn default() -> Self
