Trait FromSql 

pub trait FromSql: Sized {
    // Required method
    fn column_result(value: ValueRef<'_>) -> Result<Self, FromSqlError>;
}

A trait for types that can be created from a SQLite value.

Required Methods

fn column_result(value: ValueRef<'_>) -> Result<Self, FromSqlError>

Converts SQLite value into Rust value.

Dyn Compatibility

This trait is not dyn compatible.

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