Struct RowData 

pub struct RowData {
    pub columns: Vec<Value>,
    pub named: Option<HashMap<String, Value>>,
    pub schema: Option<Arc<Vec<String>>>,
}

Data for a table row

Fields

columns: Vec<Value>

Column values in schema order

named: Option<HashMap<String, Value>>

Named column access (optional, for convenience)

schema: Option<Arc<Vec<String>>>

Shared column schema: column names in order (maps index → name). When set, columns holds the values and named is None. This saves ~60% memory vs per-row HashMap.

Implementations

impl RowData

pub fn new(columns: Vec<Value>) -> Self

Create new row data from column values

pub fn with_names(columns: Vec<Value>, names: Vec<String>) -> Self

Create row data with named columns

pub fn get_field(&self, name: &str) -> Option<&Value>

Get a named field value — checks named HashMap first, then schema+columns.

pub fn iter_fields(&self) -> Box<dyn Iterator<Item = (&str, &Value)> + '_>

Iterate over all (name, value) pairs — works for both named and columnar.

pub fn get(&self, index: usize) -> Option<&Value>

Get column by index

pub fn get_by_name(&self, name: &str) -> Option<&Value>

Get column by name

pub fn len(&self) -> usize

Number of columns

pub fn is_empty(&self) -> bool

Check if empty
