Expand description

An EDN Value.

Variants

`Nil`

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

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

`Boolean(bool)`

A boolean value

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

`Character(char)`

A single character.

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

`String(String)`

A string. Used to represent textual data.

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

`Symbol(Symbol)`

A symbol. Used to represent identifiers.

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

`Keyword(Keyword)`

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

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

`Integer(i64)`

A signed integer

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

`Float(OrderedFloat<f64>)`

A floating point number with 64 bit precision.

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

`BigInt(BigInt)`

An integer with arbitrary precision

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

`BigDec(BigDecimal)`

A decimal number with exact precision

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

`List(Vec<Value>)`

A list of values.

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

`Vector(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>)`

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>)`

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>)`

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)`

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>)`

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.
