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.

Simple(SimpleCommand)

A simple command with optional assignments, words, and redirections.

Subshell(SubshellCommand)

A ( compound_list ) subshell.

Group(GroupCommand)

A { compound_list ; } brace group.

If(IfCommand)

An if / elif / else / fi construct.

While(WhileCommand)

A while condition; do body; done loop.

Until(UntilCommand)

An until condition; do body; done loop.

For(ForCommand)

A for name in words; do body; done loop.

ArithFor(ArithForCommand)

A C-style for (( init; cond; step )) do body done loop.

FunctionDef(FunctionDef)

A function definition.

Case(CaseCommand)

A case word in ... esac statement.

DoubleBracket(DoubleBracketCommand)

A [[ expression ]] extended test.

ArithCommand(ArithCommandNode)

A (( expr )) arithmetic command.

Select(SelectCommand)

A select name in words; do body; done menu loop.

Trait Implementations

impl Clone for Command

fn clone(&self) -> Command

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Command

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

Formats the value using the given formatter.

impl PartialEq for Command

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