Enum OwnedSexpr

pub enum OwnedSexpr {
    List(OwnedSexprs),
    Group(OwnedSexprs),
    String(Vec<u8>),
    Atom(Vec<u8>),
    Comment(Vec<u8>),
}

An owned version of Sexpr. You can convert to and from Sexpr using the From trait.

Display

OwnedSexpr implements the Display trait for serializing to strings. By default, the output will try to minimize the amount of spaces used and the resulting output will be on one line. Enabling the formatter’s alternate flag using #, causes the output to be human-friendly / pretty-printed. Setting the precision with . additionally allows to specify the number of spaces used for indentation (2 by default).

For example:

let sexpr = rsexpr::from_slice(b"[ a b c ]").unwrap();
assert_eq!(format!("{sexpr}"), "[a b c]");
assert_eq!(format!("{sexpr:#}"), "[
  a
  b
  c
]");
assert_eq!(format!("{sexpr:#.4}"), "[
    a
    b
    c
]");

Trait Implementations

impl Clone for OwnedSexpr

fn clone(&self) -> OwnedSexpr

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for OwnedSexpr

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

Formats the value using the given formatter.

impl Display for OwnedSexpr

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

Formats the value using the given formatter.

impl<'a> From<&'a OwnedSexpr> for Sexpr<'a>

fn from(value: &'a OwnedSexpr) -> Self

Converts to this type from the input type.

impl From<Sexpr<'_>> for OwnedSexpr

fn from(value: Sexpr<'_>) -> Self

Converts to this type from the input type.

impl FromIterator<OwnedSexpr> for OwnedSexprs

fn from_iter<T: IntoIterator<Item = OwnedSexpr>>(iter: T) -> Self

Creates a value from an iterator.

impl Hash for OwnedSexpr

fn hash<__H: Hasher>(&self, state: &mut __H)

impl PartialEq for OwnedSexpr

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