Module sql_builder 

Core SQL builder for constructing parameterized queries.

Sits at the foundation of the query module. Every other module in query/ uses SqlBuilder to accumulate SQL text and bind parameters.

Design

SqlBuilder wraps a String buffer and a Vec<SqlParam>. As SQL fragments are appended, user-supplied values are stored in the param list while the buffer receives $1, $2, … placeholders. The final build() call returns the completed SQL string paired with the ordered parameter vector, ready for sqlx::query_with.

SQL Example

-- After pushing: push("SELECT "), push_ident("name"), push(" FROM "),
--   push_qi(qi), push(" WHERE "), push_ident("age"), push(" >= "),
--   push_param(Text("18"))
SELECT "name" FROM "public"."users" WHERE "age" >= $1
