block size in bytes (default: 4096)

file_size_bytes: u64

total backing file size in bytes (default: 67108864)

read_percentage: u32

percentage of read operations (0 to 100)

fsync_every_n_ops: u64

trigger fsync every N operations (default: 0)

rate_mibs: u64

rate limit operations in MiB/s (default: 0)

seed: u64

RNG seed for reproducibility (default: 0)

Trait Implementations

impl Clone for RandomArgs

fn clone(&self) -> RandomArgs

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RandomArgs

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl FromArgs for RandomArgs

fn from_args(__cmd_name: &[&str], __args: &[&str]) -> Result<Self, EarlyExit>

Construct the type from an input set of arguments.

fn redact_arg_values( __cmd_name: &[&str], __args: &[&str], ) -> Result<Vec<String>, EarlyExit>

Get a String with just the argument names, e.g., options, flags, subcommands, etc, but without the values of the options and arguments. This can be useful as a means to capture anonymous usage statistics without revealing the content entered by the end user.

impl SubCommand for RandomArgs

const COMMAND: &'static CommandInfo

Information about the subcommand.
