Enum SExpr

pub enum SExpr {
    Atom(String),
    Binding(String, Box<SExpr>),
    List(Vec<SExpr>),
}

S-expression representation of ISLE source code prior to printing.

Variants

Atom(String)

Atom is a plain string to be printed.

Binding(String, Box<SExpr>)

A binding for an ISLE structure, e.g. x @ (...).

List(Vec<SExpr>)

A parenthesized list of S-expressions, e.g. (x y z).

Trait Implementations

impl Clone for SExpr

fn clone(&self) -> SExpr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SExpr

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

Formats the value using the given formatter.

impl PartialEq for SExpr

fn eq(&self, other: &SExpr) -> bool

Tests for self and other values to be equal, and is used by ==.

const fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
