How do you write out a string based enum for postgres using diesel?

The code I have is below. The examples I found seem to be based around diesel 1, but the documentation samples for diesel v2.X.X only offer a tiny snippet of code that by itself isn’t usable and I don’t know how to bridge the gap to a working sample.

This doesn’t need to be generic for all Backend just postgres.

#[derive(Debug, Clone, Copy, AsExpression)]
#[diesel(sql_type = Text)]
pub enum EnumStatus {
    OPEN,
    CLOSED,
}

impl<DB> ToSql<Text, DB> for EnumStatus
where
    DB: Backend,
    String: ToSql<Text, DB>,
{
    fn to_sql<'b>(&'b self, out: &mut Output<'b, '_, DB>) -> serialize::Result {
        match self {
            EnumStatus::OPEN => b"OPEN".to_sql(out),
            EnumStatus::CLOSED => b"CLOSED".to_sql(out),
        }
    }
}

impl<DB> FromSql<Text, DB> for EnumStatus
where
    DB: Backend,
    String: FromSql<Text, DB>,
{
    fn from_sql(bytes: DB::RawValue<'_>) -> deserialize::Result<Self> {
        match String::from_sql(bytes)? {
            b"OPEN" => Ok(EnumStatus::OPEN),
            b"CLOSED" => Ok(EnumStatus::CLOSED),
            x => Err(format!("Unrecognized enum - {}", x).into()),
        }
    }
}
