Struct DomainForm 

pub struct DomainForm {
    pub name: String,
    pub fields: Vec<(String, DomainValue)>,
    pub positional: Vec<DomainValue>,
}

A parsed #(name ...) form: a name, keyed fields, and positional values.

Fields

name: String

The form name.

fields: Vec<(String, DomainValue)>

Keyed key=value fields, in order.

positional: Vec<DomainValue>

Positional (un-keyed) values, in order.

Implementations

impl DomainForm

pub fn field(&self, key: &str) -> Option<&DomainValue>

The value of keyed field key, if present.

pub fn atom(&self, key: &str) -> Result<&str, DomainFormError>

The atom string of keyed field key.

pub fn string(&self, key: &str) -> Result<&str, DomainFormError>

The string of keyed field key.

pub fn list(&self, key: &str) -> Result<&[DomainValue], DomainFormError>

The list items of keyed field key.

pub fn form(&self, key: &str) -> Result<&DomainForm, DomainFormError>

The nested form of keyed field key.

pub fn field_atom_or_string(&self, name: &str) -> Result<&str, DomainFormError>

The atom or string text of keyed field key.

Accepts either a bare atom or a quoted string, returning the underlying text in both cases (the reverse of the #(...) writer, which renders a symbol as an atom and a string with quotes).

pub fn field_text(&self, name: &str) -> Result<String, DomainFormError>

The rendered render_text form of keyed field name.

Errors with MissingField when the field is absent; any present value renders (an atom to its text, a string to its quoted form, a list or nested form to its #(...)/[...] text).

Trait Implementations

impl Clone for DomainForm

fn clone(&self) -> DomainForm

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DomainForm

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

Formats the value using the given formatter.

impl PartialEq for DomainForm

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