Struct structured::Table

pub struct Table { /* fields omitted */ }

Structured data represented in a column-oriented form.

Implementations

impl Table

pub fn new(
    schema: Arc<Schema>,
    columns: Vec<Column>,
    event_ids: HashMap<u64, usize>
) -> Result<Self, &'static str>

Creates a new Table with the given schema and columns.

Errors

Returns an error if columns have different lengths.

pub fn append(&mut self, other: &mut Self)

Moves all the rows of other intot self, leaving other empty.

Panics

Panics if the types of columns are different, or the number of rows overflows usize.

pub fn columns(&self) -> Iter<'_, Column>

Returns an Iterator for columns.

pub fn num_columns(&self) -> usize

Returns the number of columns in the table.

pub fn num_rows(&self) -> usize

Returns the number of rows in the table.

pub fn statistics(
    &self,
    rows: &[usize],
    column_types: &Arc<Vec<ColumnType>>,
    r_enum_maps: &HashMap<usize, HashMap<u64, Vec<String>>>,
    time_intervals: &Arc<Vec<u32>>,
    numbers_of_top_n: &Arc<Vec<u32>>
) -> Vec<ColumnStatistics>

pub fn count_group_by(
    &self,
    rows: &[usize],
    column_types: &Arc<Vec<ColumnType>>,
    by_column: usize,
    by_interval: Option<u32>,
    count_columns: &Arc<Vec<usize>>
) -> Vec<GroupCount>

pub fn get_index_of_event(&self, eventid: u64) -> Option<&usize>

Trait Implementations

impl Clone for Table

fn clone(&self) -> Table

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Table

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

Formats the value using the given formatter.
