Trait PgRow 

pub trait PgRow {
    // Required methods
    fn get_value<T>(&self, column: &str) -> PgResult<T>
       where T: for<'a> FromSql<'a>;
    fn get_opt<T>(&self, column: &str) -> PgResult<Option<T>>
       where T: for<'a> FromSql<'a>;
    fn try_get<T>(&self, column: &str) -> Option<T>
       where T: for<'a> FromSql<'a>;
}

Extension trait for PostgreSQL rows.

Required Methods

fn get_value<T>(&self, column: &str) -> PgResult<T>

where T: for<'a> FromSql<'a>,

Get a column value by name.

fn get_opt<T>(&self, column: &str) -> PgResult<Option<T>>

where T: for<'a> FromSql<'a>,

Get an optional column value by name.

fn try_get<T>(&self, column: &str) -> Option<T>

where T: for<'a> FromSql<'a>,

Try to get a column value, returning None if the column doesn’t exist.

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.
