Module parser 

Recursive-descent parser: token stream → validated typed AST.

Structs

Parser

Canonical QQL parser facade.

RecoveredScript

A script parse that keeps going after syntax errors.

Constants

MAX_STATEMENTS

Hard upper bound for one parsed script. Callers that need larger imports should split them into bounded batches before parsing.

STRICT_MODE_KEYS

Closed key set of WITH STRICT_MODE (…) (OpenAPI StrictModeConfig).

Functions

ascii_equal

Returns true when s equals other, ignoring ASCII case.

check_deleted_threshold

Checks that deleted_threshold is a number between 0.0 and 1.0.

config_bool

Reads a boolean config value, returning None when absent or not a bool.

config_float_range

Reads a numeric config value, or None when absent or outside [min, max].

config_has_key

Returns true when the config contains the given key (case-insensitive).

config_max_optimization_threads

Reads a thread count as a positive integer or the string auto.

config_non_negative_u64

Reads a non-negative integer config value; None when absent, error when invalid.

config_positive_u64

Reads a positive integer config value; None when absent, error when invalid.

config_value

Looks up a config entry by key, comparing ASCII case-insensitively.

is_contextual_field_name

Returns true when a token kind can serve as a contextual field name.

is_strict_mode_key

True when key names a STRICT_MODE option (case-insensitive).

merge_collection_config

Merges new collection config clauses into current, erroring on duplicates.

validate_hnsw_value

Type-checks one HNSW config option (m, ef_construct, on_disk, memory, …).

validate_index_options

Type-checks CREATE INDEX options, erroring on unknown keys or bad value types.

validate_optimizers_value

Type-checks one optimizers config option (deleted_threshold, memmap_threshold, …).

validate_params_value

Type-checks one collection PARAMS option (replication, sharding, memory, …).

validate_strict_mode_value

Type-checks one strict-mode config option by shape (ranges are enforced at plan time so hand-built ASTs fail closed there too).

validate_vectors_value

Type-checks one vectors config option (on_disk, memory, datatype).

validate_wal_value

Type-checks one WAL config option (wal_capacity_mb, …).
