Enum SExp

pub enum SExp {
    Nil(Srcloc),
    Cons(Srcloc, Rc<SExp>, Rc<SExp>),
    Integer(Srcloc, Number),
    QuotedString(Srcloc, u8, Vec<u8>),
    Atom(Srcloc, Vec<u8>),
}

The compiler’s view of SExp.

These preserve some characteristics of the source text that aren’t strictly required for chiklisp but are useful for ergonomics and compilation. The Srcloc especially is relied on by the vscode plugin, which uses the frontend entrypoints here for parsing and to surface some kinds of errors.

Variants

Nil(Srcloc)

A native nil value “()”

Cons(Srcloc, Rc<SExp>, Rc<SExp>)

A cons with a left and right child. The srcloc should span the entire content of the list, but may not depending on the construction of the list.

Integer(Srcloc, Number)

Contains an integer which is presented normalized.

QuotedString(Srcloc, u8, Vec<u8>)

Contains a quoted string or hex constant to reproduce exactly.

Atom(Srcloc, Vec<u8>)

Contains an identifier like atom.

Trait Implementations

impl Clone for SExp

fn clone(&self) -> SExp

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SExp

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

Formats the value using the given formatter.

impl Display for SExp

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

Formats the value using the given formatter.

impl Hash for SExp

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 SExp

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
