Implementations

impl Shell

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

pub fn index(&self) -> usize

pub fn detect_default() -> Self

Detect default shell from env vars + platform.

Priority:

1. NIGHTHAWK_SHELL env var (explicit override, all platforms)
2. Parent process name via /proc (Linux/macOS only)
3. Shell version env vars like ZSH_VERSION (Unix only, rarely exported)
4. $SHELL env var (Unix only, login shell - may differ from current)
5. Platform default: PowerShell on Windows, Zsh on Unix

Note: On Windows, only NIGHTHAWK_SHELL override works reliably. The hint will always suggest PowerShell unless overridden.

pub fn detect_from( nighthawk_shell: Option<String>, zsh_version: Option<String>, bash_version: Option<String>, fish_version: Option<String>, nu_version: Option<String>, shell_env: Option<String>, ) -> Self

Pure detection function for testability — takes env values as parameters.

Priority:

1. NIGHTHAWK_SHELL override (explicit user choice)
2. Shell version env vars: ZSH_VERSION, BASH_VERSION, FISH_VERSION, NU_VERSION (set by the current shell, not inherited — detects actual running shell)
3. $SHELL fallback (login shell — may differ from current interactive shell)
4. Platform default (PowerShell on Windows, Zsh on Unix)

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 Copy for Shell

impl Debug for Shell

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Shell

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for Shell

impl FromStr for Shell

type Err = String

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for Shell

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

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.
