Trait ExtractValue 

pub trait ExtractValue: Sized {
    // Required methods
    fn extract(row: &Row, col: &str) -> OrmResult<Self>;
    fn extract_at(row: &Row, index: usize) -> OrmResult<Self>;
    fn from_pg_value(val: PgValue) -> OrmResult<Self>;
}

Required Methods

fn extract(row: &Row, col: &str) -> OrmResult<Self>

fn extract_at(row: &Row, index: usize) -> OrmResult<Self>

fn from_pg_value(val: PgValue) -> OrmResult<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.
