Enum Row 

pub enum Row {
    Integer(BTreeMap<i64, i32>),
    Text(BTreeMap<i64, String>),
    Real(BTreeMap<i64, f32>),
    Bool(BTreeMap<i64, bool>),
    None,
}

The schema for each SQL row in every table is represented in memory by following structure

This is an enum representing each of the available types organized in a BTreeMap data structure, using the ROWID and key and each corresponding type as value

Variants

Integer(BTreeMap<i64, i32>)

Text(BTreeMap<i64, String>)

Real(BTreeMap<i64, f32>)

Bool(BTreeMap<i64, bool>)

None

Implementations

impl Row

pub fn rowids(&self) -> Vec<i64>

Every column’s BTreeMap is keyed by ROWID. All columns share the same keyset after an INSERT (missing columns are padded), so any column’s keys are a valid iteration of the table’s rowids.

pub fn get(&self, rowid: i64) -> Option<Value>

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.

impl PartialEq for Row

fn eq(&self, other: &Row) -> 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.
