Struct UiArgs 

pub struct UiArgs {
    pub dry_run: bool,
    pub install_dir: Option<String>,
    pub force: bool,
}

Parsed common arguments for UI installer scripts.

Provides struct-based parsing for --dry-run, --dir <path>, --force, and --help flags, matching the behavior of ui_parse_common_args from the shell scripts.

Validation

• VAL-INFRA-015: CLI arg parsing with path validation

Fields

dry_run: bool

Whether dry-run mode is enabled.

install_dir: Option<String>

The installation directory (absolute path).

force: bool

Whether –force was specified (no-op for UI installers, accepted for compatibility).

Implementations

impl UiArgs

pub fn parse(args: &[&str]) -> Result<Self, UiArgError>

Parse command-line arguments into UiArgs.

Supports:

• --dry-run — enable dry-run mode
• --dir <path> — set installation directory (must be absolute)
• --force — accepted for compatibility (no-op for UI installers)
• --help / -h — print usage and return Err(2) (matching shell behavior)

Returns an error if:

• --dir is provided without a path argument
• --dir path is not absolute
• --dir targets a sensitive system directory

pub fn install_dir_or<'a>(&'a self, default: &'a str) -> &'a str

Get the installation directory, or a default.

impl Debug for UiArgs

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