Struct Column 

pub struct Column {
    pub column_name: String,
    pub datatype: DataType,
    pub is_pk: bool,
    pub not_null: bool,
    pub is_unique: bool,
}

The schema for each SQL column in every table.

Per-column index state moved to Table::secondary_indexes in Phase 3e — a single Column describes the declared schema (name, type, constraints) and nothing more.

Fields

column_name: String

datatype: DataType

is_pk: bool

not_null: bool

is_unique: bool

Implementations

impl Column

pub fn new( name: String, datatype: String, is_pk: bool, not_null: bool, is_unique: bool, ) -> Self

Trait Implementations

impl Clone for Column

fn clone(&self) -> Column

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Column

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

Formats the value using the given formatter.

impl PartialEq for Column

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