data_type: DataType

Logical data type.

nullable: bool

Whether the column admits NULL.

is_primary: bool

true when this column is part of the primary key.

is_foreign: bool

true when this column is part of (any) foreign key.

is_unique: bool

true when this column is part of a single-column UNIQUE constraint.

default: Option<String>

Optional default value, rendered verbatim into DDL.

comment: String

Optional descriptive comment.

Implementations

impl Column

pub fn new(id: ColumnId, name: impl Into<String>, data_type: DataType) -> Self

Construct a non-key, non-null column.

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<'de> Deserialize<'de> for Column

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

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.

impl Serialize for Column

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
