Variants

Assignment(Assignment)

Variable assignment: NAME=value or local NAME = value

Command(Command)

Simple command: tool arg1 arg2

Pipeline(Pipeline)

Pipeline: a | b | c

If(IfStmt)

Conditional: if cond; then ...; fi

For(ForLoop)

Loop: for X in items; do ...; done

While(WhileLoop)

While loop: while cond; do ...; done

Case(CaseStmt)

Case statement: case expr in pattern) ... ;; esac

Break(Option<usize>)

Implementations

impl Stmt

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

Human-readable variant name for tracing spans.

Trait Implementations

impl Clone for Stmt

fn clone(&self) -> Stmt

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Stmt

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

Formats the value using the given formatter.

impl PartialEq for Stmt

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