}

The one-byte tag that prefixes each node in a frame body.

Each variant selects the Expr shape that follows and fixes its wire layout. The discriminant is the on-wire byte; decoding rejects any byte without a matching variant.

Variants

Nil = 0

The nil value; no payload.

False = 1

The boolean false; no payload.

True = 2

The boolean true; no payload.

Number = 3

A number: a number-domain table index then the canonical text.

Symbol = 4

A symbol, given as an index into the symbol table.

String = 5

A UTF-8 string, length-prefixed.

Bytes = 6

A raw byte blob, length-prefixed.

List = 7

A list: a count then that many body nodes.

Vector = 8

A vector: a count then that many body nodes.

Map = 9

A map: a count then that many canonically ordered key/value node pairs.

Set = 10

A set: a count then that many canonically ordered body nodes.

Call = 11

A call: an operator node, a count, then that many argument nodes.

Infix = 12

An infix application: an operator symbol index then left and right nodes.

Prefix = 13

A prefix application: an operator symbol index then the argument node.

Postfix = 14

A postfix application: an operator symbol index then the argument node.

Block = 15

A block: a count then that many body nodes.

Quote = 16

A quote: a quote-mode byte then the quoted node.

Annotated = 17

An annotated node: the inner node then a count of symbol/value pairs.

Extension = 18

An extension: a tag symbol index then the payload node.

Local = 19

A local binding reference, given as an index into the symbol table.

Trait Implementations

impl Clone for BinaryTag

fn clone(&self) -> BinaryTag

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for BinaryTag

impl Debug for BinaryTag

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

Formats the value using the given formatter.

impl Eq for BinaryTag

impl PartialEq for BinaryTag

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