An EDN Value.

Variants

Nil

nil. Analogous to null, nothing, zip, zilch, and nada.

https://github.com/edn-format/edn#nil

Boolean(bool)

Tuple Fields

0: bool

A boolean value

https://github.com/edn-format/edn#booleans

Character(char)

Tuple Fields

0: char

A single character.

https://github.com/edn-format/edn#characters

String(String)

Tuple Fields

0: String

A string. Used to represent textual data.

https://github.com/edn-format/edn#strings

Symbol(Symbol)

Tuple Fields

0: Symbol

A symbol. Used to represent identifiers.

https://github.com/edn-format/edn#symbols

Keyword(Keyword)

Tuple Fields

0: Keyword

A keyword. An identifier that designates itself. For typical use, these should be used for keys in Value::Map instead of Value::String.

Integer(i64)

Tuple Fields

0: i64

A signed integer

https://github.com/edn-format/edn#integers

Float(OrderedFloat<f64>)

Tuple Fields

0: OrderedFloat<f64>

A floating point number with 64 bit precision.

https://github.com/edn-format/edn#floating-point-numbers

BigInt(BigInt)

Tuple Fields

0: BigInt

An integer with arbitrary precision

https://github.com/edn-format/edn#integers

BigDec(BigDecimal)

Tuple Fields

0: BigDecimal

A decimal number with exact precision

https://github.com/edn-format/edn#floating-point-numbers

List(Vec<Value>)

Tuple Fields

0: Vec<Value>

A list of values.

https://github.com/edn-format/edn#lists

Vector(Vec<Value>)

Tuple Fields

0: Vec<Value>

A vector of values. The major difference between this and a Value::List is that a vector is guaranteed by the spec to support random access of elements. In this implementation the semantic difference is maintained, but the underlying data structure for both is a Vec, which supports random access.

https://github.com/edn-format/edn#vectors

Map(BTreeMap<Value, Value>)

Tuple Fields

0: BTreeMap<Value, Value>

A collection of associations between keys and values. Supports any EDN value as a key. No semantics should be associated with the order in which the pairs appear.

https://github.com/edn-format/edn#maps

Set(BTreeSet<Value>)

Tuple Fields

0: BTreeSet<Value>

A collection of unique values. No semantics should be associated with the order the items appear.

https://github.com/edn-format/edn#sets

Inst(DateTime<FixedOffset>)

Tuple Fields

0: DateTime<FixedOffset>

An instant in time. Represented as a tagged element with tag inst and value a RFC-3339 formatted string.

https://github.com/edn-format/edn#inst-rfc-3339-format

Uuid(Uuid)

Tuple Fields

0: Uuid

A UUID. Represented as a tagged element with tag uuid and value a canonical UUID string.

https://github.com/edn-format/edn#uuid-f81d4fae-7dec-11d0-a765-00a0c91e6bf6

TaggedElement(Symbol, Box<Value>)

Tuple Fields

0: Symbol

1: Box<Value>

A tagged element. This can be used to encode any kind of data as a distinct readable element, with semantics determined by the reader and writer.

Overriding the behavior of elements tagged with inst and uuid is not supported in this implementation.
