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".

Implementations on Foreign Types

impl FromValue for String

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

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<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.
