Enum Argv0LinkMethod 

#[non_exhaustive]
pub enum Argv0LinkMethod {
    SoftLink,
    HardLink,
    Script,
}

On-disk mechanism used by Cli::create_link to materialize an alternative argv[0] name so the binary can be invoked under it.

Installers pick the mechanism that suits the platform and environment; self-healing code can re-run Cli::create_link to restore a deleted link.

Non-exhaustive: more link mechanisms may be added in future releases.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

SoftLink

A symbolic link to the target executable (<name> on Unix, <name>.exe on Windows). On Windows this may require Developer Mode or elevation.

HardLink

A hard link to the target executable (<name> on Unix, <name>.exe on Windows). The link must live on the same volume as the target.

Script

A small shim script that forwards to the target via the argv0 command: a <name>.cmd batch file on Windows, or an executable <name> shell script on Unix. Useful when links are unavailable or inconvenient.

Trait Implementations

impl Clone for Argv0LinkMethod

fn clone(&self) -> Argv0LinkMethod

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Argv0LinkMethod

impl Debug for Argv0LinkMethod

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

Formats the value using the given formatter.

impl Eq for Argv0LinkMethod

impl PartialEq for Argv0LinkMethod

fn eq(&self, other: &Argv0LinkMethod) -> 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.
