Struct SqlContext 

pub struct SqlContext<'ctx, 'conn> { /* private fields */ }

Host SQL inside one journaled write transaction.

The context exposes SQL operations, but never the underlying SQLite connection or transaction. In particular, a host cannot remove coven’s SQL authorizer and address its attached gate baseline:

handle.sql(|sql| {
    sql.tx().authorizer(
        None::<fn(coven::rusqlite::hooks::AuthContext<'_>)
            -> coven::rusqlite::hooks::Authorization>,
    )?;
    Ok(())
}).await?;

impl<'ctx, 'conn> SqlContext<'ctx, 'conn>

pub fn execute<P>(&self, sql: &str, params: P) -> Result<usize>

where P: Params,

pub fn execute_batch(&self, sql: &str) -> Result<()>

Execute one or more semicolon-separated SQL statements.

pub fn query_row<T, P, F>(&self, sql: &str, params: P, map: F) -> Result<T>

where P: Params, F: FnOnce(&Row<'_>) -> Result<T>,

pub fn query<T, P, F>(&self, sql: &str, params: P, map: F) -> Result<Vec<T>>

where P: Params, F: FnMut(&Row<'_>) -> Result<T>,

Query any number of rows and collect their mapped host values.
