Implementations

impl CompletionShell

pub fn detect() -> CompletionShell

Detects the current shell from environment variables.

Checks in order:

1. NU_VERSION env var (indicates Nushell)
2. SHELL env var (parses the shell name from the path)

Falls back to Bash if detection fails.

pub fn all() -> &'static [CompletionShell]

Returns all supported shell variants.

Trait Implementations

impl Clone for CompletionShell

fn clone(&self) -> CompletionShell

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for CompletionShell

impl Debug for CompletionShell

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

Formats the value using the given formatter.

impl Default for CompletionShell

fn default() -> CompletionShell

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for CompletionShell

fn deserialize<__D>( __deserializer: __D, ) -> Result<CompletionShell, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for CompletionShell

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

Formats the value using the given formatter.

impl Eq for CompletionShell

impl FromStr for CompletionShell

type Err = ParseShellError

The associated error which can be returned from parsing.

fn from_str( s: &str, ) -> Result<CompletionShell, <CompletionShell as FromStr>::Err>

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

impl Hash for CompletionShell

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

where __H: Hasher,

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 CompletionShell

fn eq(&self, other: &CompletionShell) -> 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 CompletionShell

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl StructuralPartialEq for CompletionShell

impl ValueEnum for CompletionShell

fn value_variants<'a>() -> &'a [CompletionShell]

All possible argument values, in display order.

fn to_possible_value(&self) -> Option<PossibleValue>

The canonical argument value.

fn from_str(input: &str, ignore_case: bool) -> Result<Self, String>

Parse an argument into Self.
