Struct Row 

pub struct Row {
    pub columns: Vec<String>,
    pub values: Vec<ColumnValue>,
}

A single data row with named columns.

Columns are stored in insertion order; lookup by name performs a linear scan which is fast for the typical column counts in tabular data.

Fields

columns: Vec<String>

Column names in order.

values: Vec<ColumnValue>

Values aligned with columns.

Implementations

impl Row

pub fn from_pairs(pairs: Vec<(String, ColumnValue)>) -> Self

Construct a row from a Vec<(name, value)> list.

pub fn get(&self, column: &str) -> Option<&ColumnValue>

Look up a value by column name. Returns None when the column is absent.

pub fn is_empty(&self) -> bool

Returns true when the row contains no columns.

pub fn len(&self) -> usize

Number of columns in this row.

pub fn iter(&self) -> impl Iterator<Item = (&str, &ColumnValue)>

Return an iterator over (column_name, value) pairs.

Trait Implementations

impl Clone for Row

fn clone(&self) -> Row

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Row

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

Formats the value using the given formatter.
