Enum Shell 

pub enum Shell {
    Bash,
    Zsh,
}

Which shell we’re targeting. Detected from $SHELL for the bare show/install flow; the user can override with --shell at the CLI layer.

Variants

Bash

Zsh

Implementations

impl Shell

pub fn detect() -> Option<Self>

Detect from $SHELL. Returns None when $SHELL is unset or names a shell we don’t support — the caller (typically resolve_shell) surfaces a clear error rather than silently writing a bashrc snippet for a fish/nu user.

Why fail explicitly: silently falling back to Bash means dodot git-install-alias happily writes ~/.bashrc for a fish user, who then never sees the alias take effect. Better to refuse with a message that points at --shell.

pub fn from_str_opt(s: &str) -> Option<Self>

Parse a CLI --shell value. Returns None for unknown shells; the CLI layer surfaces a clear error.

pub fn rc_relative_path(self) -> &'static str

Path to the rc file we write to for this shell, relative to $HOME. Used by install_alias to compute the absolute path. We pick the most universally-sourced file: .bashrc on bash, .zshrc on zsh. Users with non-standard setups can run git-show-alias and paste manually.

pub fn alias_line(self) -> &'static str

The alias line for this shell. Both bash and zsh accept the same alias syntax; we pin them per-shell anyway because future shells (fish, nu) will need different forms and keeping the dispatch on a single match is the cleanest extension point.

Trait Implementations

impl Clone for Shell

fn clone(&self) -> Shell

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Shell

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

Formats the value using the given formatter.

impl PartialEq for Shell

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

impl Serialize for Shell

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Shell

impl Eq for Shell
