* feat: Identifier → VarRef, which represents a tag or field reference InfluxQL calls these variables, so the Rust parser will follow precedent. * chore: Add docs * chore: Separate arithmetic and conditional expression parsing This is necessary to ensure conditional expressions are only supported in a `WHERE` clause and arithmetic expressions in `SELECT` field projection list * feat: Add a `verify` API to transform combinator functions to errors This is useful to preform additional validation on a valid result. * feat: Add customisation for operand parsing to arithmetic expressions This permits narrowing of valid function calls in `WHERE` clauses and to customise valid operands in a `SELECT` projection, such as a wildcard (`*`) * chore: move logic to appropriate modules. * feat: Add wildcard discriminator to Expr enum required for `SELECT` * chore: Remove dead_code attribute * feat: Add `DISTINCT` operator * chore: Add `distinct` macro; simplify existing macros * chore: add assert_matches; parse Field and Field list; refactor literal * feat: Add a new type to parse a separated_list1 into a specialised type * chore: Refactor types using `separated_list1` * chore: Ensure items in a list can be preceded by a space * chore: Refactor IN clause to use OneOrMore * feat: Parse `GROUP BY` clause * chore: appease clippy * chore: refactor number parsing to share code; add signed Number type * feat: completed `SELECT` statement parser. * chore: Consistent error messages when expecting tokens * chore: Add recommended derive implementations * feat: Add `SELECT` statement to `statement` combinator * chore: Refactor OneOrMore::separated_list1 to a single error message * chore: More tests and cleanup 🧹 * chore: More tests * chore: Appease broken doc links checker * chore: remove remaining `dead_code` attributes 🥳 * chore: Address PR feedback * https://github.com/influxdata/influxdb_iox/pull/5692#discussion_r982559420 * https://github.com/influxdata/influxdb_iox/pull/5692#discussion_r982527476 * chore: Address PR feedback * https://github.com/influxdata/influxdb_iox/pull/5692#discussion_r982626857 * https://github.com/influxdata/influxdb_iox/pull/5692#discussion_r982569760 * chore: Address PR feedback for Display implementations Also removed duplicate test case |
