Struct PrimaryKey 

pub struct PrimaryKey {
    pub schema: Cow<'static, str>,
    pub table: Cow<'static, str>,
    pub name: Cow<'static, str>,
    pub name_explicit: bool,
    pub columns: Cow<'static, [Cow<'static, str>]>,
}

A primary key, as stored in migration snapshots.

Fields

schema: Cow<'static, str>

Schema name

table: Cow<'static, str>

Parent table name

name: Cow<'static, str>

Constraint name

name_explicit: bool

Whether the constraint name was explicitly specified

columns: Cow<'static, [Cow<'static, str>]>

Columns in the primary key

Implementations

impl PrimaryKey

pub fn new( schema: impl Into<Cow<'static, str>>, table: impl Into<Cow<'static, str>>, name: impl Into<Cow<'static, str>>, columns: impl Into<Cow<'static, [Cow<'static, str>]>>, ) -> Self

Creates a primary key.

pub fn from_strings( schema: String, table: String, name: String, columns: Vec<String>, ) -> Self

Creates a primary key from owned strings.

pub fn schema(&self) -> &str

Returns the schema name.

pub fn name(&self) -> &str

Returns the constraint name.

pub fn table(&self) -> &str

Returns the table name.

pub const fn explicit_name(self) -> Self

impl PrimaryKey

pub fn to_constraint_sql(&self) -> String

Renders CONSTRAINT name PRIMARY KEY(...).

pub fn add_pk_sql(&self) -> String

Renders ALTER TABLE ... ADD CONSTRAINT ... PRIMARY KEY(...);.

pub fn drop_pk_sql(&self) -> String

Renders ALTER TABLE ... DROP CONSTRAINT ...;.
