Struct Column

pub struct Column { /* private fields */ }

A column’s metadata.

Implementations

impl Column

pub fn new( name: BoundedString, data_type: DataType, options: Vec<ColumnOptionDef>, internal: bool, ) -> Self

pub fn name(&self) -> &BoundedString

Name of the column.

pub fn data_type(&self) -> &DataType

Data type of the column.

pub fn options(&self) -> &Vec<ColumnOptionDef>

Column’s options (attributes, constraints, etc.).

pub fn add_column_option(&mut self, option: ColumnOptionDef)

Add a new column option.

pub fn is_internal(&self) -> bool

Whether the column is a hidden, internal-only column.

Trait Implementations

impl Clone for Column

fn clone(&self) -> Column

Returns a duplicate of the value.

const 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 Hash for Column

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Column

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

Tests for self and other values to be equal, and is used by ==.

const fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
