pub trait FromValue: Sized {
// Required method
fn from_value(value: &Value) -> Result<Self>;
}Expand description
Converts a Value to a concrete Rust type.
Implemented for common types like i64, f64, String, and bool.
Used by QueryResult::scalar() to extract typed values.
Required Methods§
Sourcefn from_value(value: &Value) -> Result<Self>
fn from_value(value: &Value) -> Result<Self>
Attempts the conversion, returning an error on type mismatch.
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.
