Derive Macro PgComposite 

#[derive(PgComposite)]
{
    // Attributes available to this derive:
    #[orm]
}

Derive PgComposite helpers to map a Rust struct to a PostgreSQL composite type.

Example

use pgorm::PgComposite;

#[derive(PgComposite, Debug, Clone)]
#[orm(pg_type = "address")]
pub struct Address {
    pub street: String,
    pub city: String,
    pub zip_code: String,
    pub country: String,
}

Generated

• impl ToSql for Address
• impl<'a> FromSql<'a> for Address
• impl PgType for Address (returns "{pg_type}[]")

Attributes

Struct-level:

• #[orm(pg_type = "name")] - PostgreSQL composite type name (required)

Limitations

• Only flat structs with named fields are supported.
• Nested composite types are not supported.
• All fields must implement ToSql and FromSql.
