Enum DomainValue 

pub enum DomainValue {
    Form(DomainForm),
    List(Vec<DomainValue>),
    String(String),
    Atom(String),
}

A parsed domain-form value.

Variants

Form(DomainForm)

A nested #(...) form.

List(Vec<DomainValue>)

A [...] list.

String(String)

A "..." string.

Atom(String)

A bare atom (number, identifier, 4/4, …).

Implementations

impl DomainValue

pub fn as_form(&self) -> Result<&DomainForm, DomainFormError>

The nested form, if this value is a #(...) form.

Errors with WrongValueKind for a list, string, or atom.

pub fn atom_or_string(&self) -> Result<&str, DomainFormError>

The text of this value when it is a bare atom or a quoted string.

Errors with WrongValueKind for a list or nested form.

pub fn render_text(&self) -> String

Renders this value back to its ASCII #(...) source text: an atom to its literal text, a string to its escaped quoted form, a list to [a,b,...], and a nested form via format_domain_form.

Round-trips through parse_domain_form for a top-level form value.

Trait Implementations

impl Clone for DomainValue

fn clone(&self) -> DomainValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DomainValue

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

Formats the value using the given formatter.

impl PartialEq for DomainValue

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