Struct Sexpr

pub struct Sexpr<'a> {
    pub ops: Vec<Box<Expr<'a>>>,
}

An AST node for an S-expression

Fields

ops: Vec<Box<Expr<'a>>>

The operands of this S-expression. Stored in reverse order, i.e. f(5) is represented as the list [5, f].

Implementations

impl<'a> Sexpr<'a>

pub fn push<T>(&mut self, op: T)

where T: Into<Box<Expr<'a>>>,

Push an operand to this S-expression

Trait Implementations

impl<'a> Clone for Sexpr<'a>

fn clone(&self) -> Sexpr<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Sexpr<'_>

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

Formats the value using the given formatter.

impl Display for Sexpr<'_>

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

Formats the value using the given formatter.

impl<'a> From<Vec<Box<Expr<'a>>>> for Sexpr<'a>

fn from(ops: Vec<Box<Expr<'a>>>) -> Sexpr<'a>

Converts to this type from the input type.

impl<'a> PartialEq for Sexpr<'a>

fn eq(&self, other: &Sexpr<'a>) -> 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.
