Trait SqlxValue 

pub trait SqlxValue: Sized {
    const KIND: ColumnKind;

    // Required methods
    fn null() -> SqlValue;
    fn into_sql_value(self) -> SqlValue;
    fn from_sql_value(value: SqlValue) -> Result<Self, ValueTypeError>;

    // Provided method
    fn prepare(self, _engine: Engine) -> AuthResult<Self> { ... }
}

A model field type which converts to and from a bound SqlValue.

Conversions preserve the field representation: strings accept TEXT and explicitly selected bpchar values; optional fields accept their typed NULL. AuthEntity uses this to stage additional fields and to materialize models without a database round trip.

Required Associated Constants

const KIND: ColumnKind

The column category used to coerce configured raw values.

Required Methods

fn null() -> SqlValue

The typed NULL of this field type.

fn into_sql_value(self) -> SqlValue

fn from_sql_value(value: SqlValue) -> Result<Self, ValueTypeError>

Errors

Returns an error if the value has a different type.

Provided Methods

fn prepare(self, _engine: Engine) -> AuthResult<Self>

Prepare a staged value for engine, after application hooks and before the write. JSON metadata binds exact JavaScript text on SQLite; every other value is bound unchanged.

Errors

Returns an error if the value cannot be serialized for engine.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
