You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: params.rs
    path of file: ./repos/libsql/vendored/rusqlite/src
    
    the code of the file until where you have to start completion: use crate::{Result, Statement, ToSql};

mod sealed {
    /// This trait exists just to ensure that the only impls of `trait Params`
    /// that are allowed are ones in this crate.
    pub trait Sealed {}
}
use sealed::Sealed;

/// Trait used for [sets of parameter][params] passed into
    
/// fn query(conn: &Connection, ids: &BTreeSet<String>) -> Result<()> {
///     assert_eq!(ids.len(), 3, "Unrealistic sample code");
///
///     let mut stmt = conn.prepare("SELECT * FROM users WHERE id IN (?1, ?2, ?3)")?;
///     let _rows = stmt.query(params_from_iter(ids.iter()))?;
///
///     // use _rows...
///     Ok(())
/// }
