Implementations

impl ShellType

pub fn variants() -> Vec<Self>

Return a list of all shell types.

pub fn os_variants() -> Vec<Self>

Return a list of shell types for the current operating system.

pub fn detect() -> Option<Self>

Detect the current shell by inspecting the $SHELL environment variable, and the parent process hierarchy.

pub fn detect_with_fallback() -> Self

Detect the current shell by inspecting the $SHELL environment variable, and the parent process hierarchy. If no shell could be find, return a fallback.

pub fn try_detect() -> Result<Self, ShellError>

Detect the current shell by inspecting the $SHELL environment variable, and the parent process hierarchy, and return an error if not detected.

pub fn build(&self) -> BoxedShell

Build a Shell instance from the current type.

Trait Implementations

impl Clone for ShellType

fn clone(&self) -> ShellType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ShellType

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

Formats the value using the given formatter.

impl Default for ShellType

fn default() -> Self

Returns the “default value” for a type.

impl Display for ShellType

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

Formats the value using the given formatter.

impl FromStr for ShellType

type Err = ShellError

The associated error which can be returned from parsing.

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

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

impl PartialEq for ShellType

fn eq(&self, other: &ShellType) -> 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 TryFrom<&str> for ShellType

type Error = ShellError

The type returned in the event of a conversion error.

fn try_from(value: &str) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<String> for ShellType

type Error = ShellError

The type returned in the event of a conversion error.

fn try_from(value: String) -> Result<Self, Self::Error>

Performs the conversion.

impl Copy for ShellType

impl Eq for ShellType

impl StructuralPartialEq for ShellType
