Trait FromSql 

pub trait FromSql<'a>: Sized {
    // Required method
    fn from_sql(value: ValueRef<'a>) -> FromSqlResult<Self>;
}

Required Methods

fn from_sql(value: ValueRef<'a>) -> FromSqlResult<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.
