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>]>,
}

Runtime primary key constraint entity

Uses Cow<'static, str> for all string fields, which works with both:

• Borrowed data from const definitions (Cow::Borrowed)
• Owned data from deserialization/introspection (Cow::Owned)

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

Create a new primary key

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

Create a new primary key from owned strings (convenience for runtime construction)

pub fn schema(&self) -> &str

Get the schema name

pub fn name(&self) -> &str

Get the constraint name

pub fn table(&self) -> &str

Get the table name

pub fn explicit_name(self) -> Self

Mark the name as explicitly specified

impl PrimaryKey

pub fn to_constraint_sql(&self) -> String

Generate the PRIMARY KEY constraint clause

pub fn add_pk_sql(&self) -> String

Generate ADD PRIMARY KEY SQL

pub fn drop_pk_sql(&self) -> String

Generate DROP PRIMARY KEY SQL

Trait Implementations

impl Clone for PrimaryKey

fn clone(&self) -> PrimaryKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PrimaryKey

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

Formats the value using the given formatter.

impl Default for PrimaryKey

fn default() -> Self

Returns the “default value” for a type.

impl From<PrimaryKeyDef> for PrimaryKey

fn from(def: PrimaryKeyDef) -> Self

Converts to this type from the input type.

impl PartialEq for PrimaryKey

fn eq(&self, other: &PrimaryKey) -> 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.
