Fields

name: String

rust_type: String

The Rust type as written, with Option unwrapped (NaiveDateTime).

ty: SqlType

nullable: bool

primary_key: bool

unique: bool

json: bool

Stored as TEXT through serde (#[orm(json)]).

is_enum: bool

Column holds a value stored as TEXT via as_str()/FromStr: a #[derive(DbEnum)] (with a CHECK from check_in) or an #[orm(text)] type (no CHECK).

index: bool

#[orm(index)] — a plain (non-unique) index on this column.

default: Option<DefaultValue>

references: Option<ForeignKey>

check_in: Option<Vec<String>>

Allowed values (from the enum) — rendered as a CHECK constraint.

renamed_from: Option<String>

One-shot rename marker: #[orm(renamed_from = "old")]. Remove the attribute once the generated migration has been applied.

Implementations

impl ColumnDef

pub fn signature(&self) -> ColumnDef

The column identity used for change detection — everything except the transient rename marker and the index flag (index changes are plain CREATE/DROP INDEX statements, never a rebuild by themselves).

Trait Implementations

impl Clone for ColumnDef

fn clone(&self) -> ColumnDef

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ColumnDef

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ColumnDef

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ColumnDef

fn eq(&self, other: &ColumnDef) -> 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 ColumnDef

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
