Struct RustShape 

pub struct RustShape { /* private fields */ }

Interprets a shape as a Rust layout whose serialization writes names this way.

A field is named in snake case, as Rust names one, and the spelling the surface writes is stated once for the whole declaration — which is available to state because the term carries words and not a spelling.

Implementations

impl RustShape

pub fn new(wire: Spelling) -> Self

Emits layouts whose serialization spells names this way.

pub fn known(self, words: Words<'_>, path: impl Into<String>) -> Self

States that a name is already a type here, and what it is called.

A domain’s leaves are not the primitives they are written as: two of them may share int(false, 64) and remain different types. A name is what tells them apart, so a name this host already has a type for is written as that type rather than declared again.

Trait Implementations

impl Clone for RustShape

fn clone(&self) -> RustShape

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RustShape

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

Formats the value using the given formatter.

impl FieldAlg for RustShape

fn field(&self, words: Words<'_>, shape: Layout) -> RustMember

A member under the name it is written with.

fn merge(&self, shape: Layout) -> RustMember

Another product’s members, observed as this product’s own.

impl ShapeAlg for RustShape

fn truth(&self) -> Layout

A boolean.

fn unit(&self) -> Layout

The empty value: null, or an absent member.

fn text(&self) -> Layout

Text.

fn literal(&self, _text: &str) -> Layout

One fixed piece of text, as a value: content that happens to be constant.

fn name_word(&self, _words: Words<'_>) -> Layout

A value whose content is a name, spelled however the interpretation spells names.

fn int(&self, signed: bool, bits: u16) -> Layout

An integer of a stated width and signedness.

fn float(&self, bits: u16) -> Layout

A floating-point number of a stated width.

fn bytes(&self, len: Option<usize>) -> Layout

Opaque bytes, of a stated length when fixed.

fn hex(&self, item: Layout) -> Layout

Written as 0x-prefixed hexadecimal, rather than however the item would appear alone.

fn decimal(&self, item: Layout) -> Layout

Written as decimal digits in text, which is what a width beyond a JSON number requires.

fn base64(&self, item: Layout) -> Layout

Written as base64 text.

fn opt(&self, item: Layout) -> Layout

A value that may be absent.

fn seq(&self, item: Layout) -> Layout

An ordered sequence of one shape.

fn map(&self, key: Layout, value: Layout) -> Layout

An association from one shape to another.

fn product(&self, fields: Vec<RustMember>) -> Layout

A product of members.

fn choice(&self, alternatives: Vec<Layout>) -> Layout

A choice between alternatives, carrying no discriminant of its own.

fn named(&self, words: Words<'_>, body: Layout) -> Layout

Introduces a name for a shape, so an interpretation can state it once.

fn reference(&self, words: Words<'_>) -> Layout

Uses a name introduced elsewhere, which is what makes recursion expressible.

impl Sorts for RustShape

type Ty = Layout

A shape.

type Field = RustMember

One member of a product.
