Fields

database: Option<PathBuf>

Database file path

config: Option<PathBuf>

Load config (TOML/YAML/JSON). Precedence: flags > env > file > defaults

verbose: u8

Verbose output (-v, -vv, -vvv for increasing verbosity)

quiet: bool

Quiet mode (suppress non-essential output)

format: OutputFormat

Output format

auto_detect: bool

Enable best-effort auto detection (format/version) when available

cassandra_version: Option<String>

Hint (e.g., 5.0) for format compatibility

schema: Option<PathBuf>

CQL (.cql) or JSON (.json) schema files; triggers schema loading for ingestion. When combined with –data-dir, enables schema-aware query execution. Repeatable; order defines precedence

dataset: Option<String>

Dataset name for test data (e.g., test_basic, test_collections) Mutually exclusive with –data-dir. Looks for datasets in CQLITE_DATASETS_ROOT/sstables/{dataset}/

data_dir: Option<PathBuf>

Cassandra data directory root (e.g., /var/lib/cassandra/data). Combined with –schema, triggers dataset discovery and ingestion. Mutually exclusive with –dataset. For production Cassandra directory layouts.

execute: Option<String>

Execute a single CQL statement in one-shot mode (alias: –query)

file: Option<PathBuf>

Execute statements from a file (semicolon-terminated)

out: Option<OutputMode>

Output format for query results. Takes precedence over –format when specified. Applies to: –execute/-e, –query, –file, and query subcommand. (table = cqlsh-compatible format)

output: Option<PathBuf>

Output file path for query results. If not specified, output goes to stdout. Required when format is ‘parquet’ (binary format cannot be written to stdout).

overwrite: bool

Overwrite output file if it exists (default: error if file exists)

limit: Option<usize>

Cap rows

page_size: Option<usize>

Reader and display pagination size

no_color: bool

Disable colored output

enable_select_fallback: bool

EXPERIMENTAL: Fallback to read-sstable for SELECT when ingestion unavailable (temporary, will be removed in M3)

writable: bool

Enable write mode (requires –write-dir)

write_dir: Option<PathBuf>

Directory for write operations (WAL and SSTable output)

mutation: Vec<String>

JSON mutation to write (can be repeated). Requires –writable mode. Format: {“table”:“ks.tbl”,“partition_key”:{“col”:“val”},“operations”:[{“Write”:{“column”:“c”,“value”:“v”}}],“timestamp_micros”:123}

mutations_file: Option<PathBuf>

File containing mutations (JSONL format, one JSON mutation per line). Requires –writable mode.

flush: bool

Force flush memtable to SSTable after writes. Requires –writable mode.

command: Option<Commands>

Trait Implementations

impl Args for Cli

fn group_id() -> Option<Id>

Report the ArgGroup::id for this set of arguments

fn augment_args<'b>(__clap_app: Command) -> Command

Append to Command so it can instantiate Self via FromArgMatches::from_arg_matches_mut

fn augment_args_for_update<'b>(__clap_app: Command) -> Command

Append to Command so it can instantiate self via FromArgMatches::update_from_arg_matches_mut

impl CommandFactory for Cli

fn command<'b>() -> Command

Build a Command that can instantiate Self.

fn command_for_update<'b>() -> Command
