Enum Value 

pub enum Value {
    Null(NullKind),
    Bool(bool),
    I64(i64),
    Text(String),
    Blob(Vec<u8>),
    Uuid(Uuid),
}

One bound parameter, in the only six shapes this schema stores.

Timestamps are Value::I64 epoch seconds, not a date type — see the module doc. JSON columns are Value::Text.

Variants

Null(NullKind)

An absent value, carrying the type of the column it is bound to.

SQLite has no typed null: a bound None is NULL whatever the caller had in mind. PostgreSQL sends a type OID with every parameter and refuses column "eab_kid" is of type uuid but expression is of type bigint, so the type an absent value would have had has to survive the trip. Every bind site knows it statically — Option<Uuid> is Null(NullKind::Uuid) — so nothing has to be declared twice.

Bool(bool)

I64(i64)

Text(String)

Blob(Vec<u8>)

Uuid(Uuid)

Trait Implementations

impl Bind for Value

A value that has already been through this enum once.

What crate::transfer binds: it reads a column at the type its manifest declares, carries it as a Value, and writes it back without ever naming a Rust type again. The identity impl is what lets the copy stay one loop over 140 columns instead of a match per column.

fn to_value(self) -> Value

impl Clone for Value

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Value

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

Formats the value using the given formatter.

impl PartialEq for Value

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
