Struct Table 

pub struct Table {
    pub id: TableId,
    pub name: String,
    pub columns: IndexMap<ColumnId, Column>,
    pub constraints: IndexMap<ConstraintId, Constraint>,
    pub comment: String,
}

A relational table.

Fields

id: TableId

Unique handle within the owning model.

name: String

Table name.

columns: IndexMap<ColumnId, Column>

Columns, in author order.

constraints: IndexMap<ConstraintId, Constraint>

Constraints attached to this table (PK, UNIQUE, FK, CHECK).

comment: String

Optional descriptive comment.

Implementations

impl Table

pub fn columns_iter(&self) -> impl Iterator<Item = &Column>

Iterate the columns in author order.

pub fn primary_key(&self) -> Option<&Constraint>

Find the table’s primary-key constraint, if any.

pub fn primary_key_columns(&self) -> &[ColumnId]

IDs of the columns that compose the primary key. Empty if there is no PK or the PK is empty.

pub fn column(&self, id: ColumnId) -> Option<&Column>

Borrow a column by ID.

Trait Implementations

impl Clone for Table

fn clone(&self) -> Table

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Table

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Table

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Table

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
