Trait FromValue 

pub trait FromValue: Sized {
    // Required method
    fn from_value(v: &Value) -> Result<Self>;
}

Conversion from SQLRite’s internal Value enum into a typed Rust value. Implementations cover the common built-ins — i64, f64, String, bool, and Option<T> for nullable columns. Extend on demand.

Required Methods

fn from_value(v: &Value) -> Result<Self>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementations on Foreign Types

impl FromValue for bool

fn from_value(v: &Value) -> Result<Self>

impl FromValue for f64

fn from_value(v: &Value) -> Result<Self>

impl FromValue for i64

fn from_value(v: &Value) -> Result<Self>

impl FromValue for String

fn from_value(v: &Value) -> Result<Self>

impl<T: FromValue> FromValue for Option<T>

Nullable columns: Option<T> maps NULL → None and everything else through the inner type’s FromValue impl.

fn from_value(v: &Value) -> Result<Self>

Implementors

impl FromValue for Value

Identity impl so row.get::<_, Value>(0) works when you want untyped access.
