expected Option<&[i32]>, but found Option<&[Weekday]>

[birarvin]

Unable to figure out why am I getting this error (in title), any pointers?

I am able to fetch data correctly using explicit casting in sql query, but seeing this issue when using it in insert statement.

My assumption is that sqlx should be able to encode to an array of [i32] based on "repr" attribute on "struct Weekday" (generated encode function should be able to achieve this), but seems like either bug or I am missing something.

Followed example of enum "Weak" here.

Currently, converting explicitly to i32 element before passing it to sqlx, but that doesn't seem like idiomatic way to do it.

Postgres field type:

#[derive(PartialEq, Copy, Clone, Debug, Serialize, Deserialize, sqlx::Type)]
#[serde(rename_all = "UPPERCASE")]
#[repr(i32)]
pub enum Weekday {
    Sunday = 0,
    Monday = 1,
    Tuesday = 2,
    Wednesday = 3,
    Thursday = 4,
    Friday = 5,
    Saturday = 6,
}

sqlx::query_as!(Uuid,
                r#"
            INSERT INTO
            schedules
            (
                frequency_type,
                days_of_week,
            )
            VALUES ($1, $2)
            RETURNING schedule_id
        "#, 
            frequency_type.to_string(),
            days_of_week.as_ref().map(|v| &v[..]),
        )
        .fetch_one(&self.pool)
        .await
        .map_err(|e| e.into())
