Enum PrivilegeTool 

pub enum PrivilegeTool {
    Sudo,
    Doas,
}

What: Privilege escalation tool supported by Pacsea.

Inputs: None (enum variant selection).

Output: Identifies which privilege tool to invoke.

Details:

• Sudo uses the standard sudo binary with full feature support (stdin password, credential caching, askpass).
• Doas uses the OpenDoas binary with limited feature support (no stdin password, no credential caching).

Variants

Sudo

Standard sudo — full feature support.

Doas

OpenDoas — limited feature support (no stdin password pipe, no credential caching).

Implementations

impl PrivilegeTool

pub const fn binary_name(self) -> &'static str

What: Return the shell binary name for this tool.

Inputs: None.

Output: "sudo" or "doas".

Details: Used in command construction and which lookups.

pub const fn capabilities(self) -> PrivilegeCapabilities

What: Return the capability flags for this tool.

Inputs: None.

Output: PrivilegeCapabilities with tool-specific flags.

Details:

• sudo: all capabilities enabled.
• doas: all capabilities disabled (see module-level docs for rationale).

pub fn is_available(self) -> bool

What: Check whether this tool’s binary exists on $PATH.

Inputs: None.

Output: true if the binary is found.

Details:

• In integration test context (PACSEA_INTEGRATION_TEST=1), honors PACSEA_TEST_PRIVILEGE_AVAILABLE (comma-separated list, or "none").
• Production: delegates to which::which.

pub fn check_passwordless(self) -> Result<bool, String>

What: Check whether passwordless privilege escalation is available.

Inputs: None.

Output: Ok(true) if non-interactive execution succeeds, Err if the check itself fails.

Errors

Returns Err if the tool binary cannot be executed (e.g. not installed).

Details:

• Runs <tool> -n true (-n = non-interactive, true = no-op command).
• Both sudo and doas support the -n flag.
• In integration test context, honors PACSEA_TEST_SUDO_PASSWORDLESS.

Trait Implementations

impl Clone for PrivilegeTool

fn clone(&self) -> PrivilegeTool

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PrivilegeTool

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

Formats the value using the given formatter.

impl Display for PrivilegeTool

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

Formats the value using the given formatter.

impl PartialEq for PrivilegeTool

fn eq(&self, other: &PrivilegeTool) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
