Struct ClientArgs 

pub struct ClientArgs {
    pub config: Option<PathBuf>,
    pub endpoint: Option<String>,
    pub timeout: Option<u64>,
    pub cache_path: Option<PathBuf>,
    pub log_level: Option<LogLevel>,
    pub log_format: Option<LogFormat>,
    pub quiet: bool,
    pub max_retries: Option<u32>,
    pub retry_delay: Option<u64>,
    pub no_shared_storage: bool,
    pub transfer_chunk_size: Option<usize>,
}

Shared command line arguments for the ModelExpress client.

Adding New Arguments

This struct is the single source of truth for client CLI arguments and environment variables. It is shared between:

• The modelexpress-cli binary (via #[command(flatten)] in the Cli struct)
• Any other client binaries that need these arguments
• The ClientConfig::load() function which applies these values

When adding a new argument:

1. Add the field here with appropriate #[arg(...)] attributes
2. Include env = "MODEL_EXPRESS_..." for environment variable support
3. Update ClientConfig::load() to apply the new argument to the config
4. Add tests in the tests module below
5. Update CLI.md documentation if applicable

Short Flags

Avoid using -v as a short flag here - it’s reserved for the CLI’s --verbose flag which uses -v, -vv, -vvv counting. The CLI embeds this struct via flatten, so short flag conflicts will cause runtime panics.

Fields

config: Option<PathBuf>

Configuration file path

endpoint: Option<String>

Server endpoint

timeout: Option<u64>

Request timeout in seconds

cache_path: Option<PathBuf>

Cache path override

log_level: Option<LogLevel>

Log level (no short flag to avoid conflict with CLI’s -v/–verbose)

log_format: Option<LogFormat>

Log format

quiet: bool

Quiet mode (suppress all output except errors)

max_retries: Option<u32>

Maximum number of retries

retry_delay: Option<u64>

Retry delay in seconds

no_shared_storage: bool

Disable shared storage mode (will transfer files from server to client)

transfer_chunk_size: Option<usize>

Chunk size in bytes for file transfer when shared storage is disabled

Trait Implementations

impl Args for ClientArgs

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 Clone for ClientArgs

fn clone(&self) -> ClientArgs

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl CommandFactory for ClientArgs

fn command<'b>() -> Command

Build a Command that can instantiate Self.

fn command_for_update<'b>() -> Command

Build a Command that can update self.

impl Debug for ClientArgs

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

Formats the value using the given formatter.

impl FromArgMatches for ClientArgs

fn from_arg_matches(__clap_arg_matches: &ArgMatches) -> Result<Self, Error>

Instantiate Self from ArgMatches, parsing the arguments as needed.

fn from_arg_matches_mut( __clap_arg_matches: &mut ArgMatches, ) -> Result<Self, Error>

Instantiate Self from ArgMatches, parsing the arguments as needed.

fn update_from_arg_matches( &mut self, __clap_arg_matches: &ArgMatches, ) -> Result<(), Error>

Assign values from ArgMatches to self.

fn update_from_arg_matches_mut( &mut self, __clap_arg_matches: &mut ArgMatches, ) -> Result<(), Error>

Assign values from ArgMatches to self.

impl Parser for ClientArgs

fn parse() -> Self

Parse from std::env::args_os(), exit on error.

fn try_parse() -> Result<Self, Error>

Parse from std::env::args_os(), return Err on error.

fn parse_from<I, T>(itr: I) -> Self

where I: IntoIterator<Item = T>, T: Into<OsString> + Clone,
