Enum PkValue 

pub enum PkValue {
    Int(i64),
    BigInt(i128),
    Text(Box<str>),
    Null,
}

Primary key value representation supporting common types

Variants

Int(i64)

Integer value (covers most PKs)

BigInt(i128)

Big integer value

Text(Box<str>)

Text/string value

Null

NULL value (typically means “no dependency” for FKs)

Implementations

impl PkValue

pub fn is_null(&self) -> bool

Check if this is a NULL value

Trait Implementations

impl Clone for PkValue

fn clone(&self) -> PkValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PkValue

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

Formats the value using the given formatter.

impl Hash for PkValue

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for PkValue

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