Enum Node 

pub enum Node {
    Mapping(Vec<(Node, Node)>),
    Sequence(Vec<Node>),
    String(String),
    Null,
    Boolean(bool),
    Integer(i64),
    FloatingPoint(String),
}

A YAML schema is a combination of a set of tags and a mechanism for resolving non-specific tags.

The tags are specified in different schemas. The spec defined three main schemas: Failsafe, JSON, and Core. The tags are grouped in the following way:

• Failsafe Schema:
  • Mapping
  • Sequence
  • String
• JSON Schema:
  • Null
  • Boolean
  • Integer
  • Floating Point

Note

The YAML specification defines nodes and tags a two separate (but related) concepts. Because Rust allows us to combine enums with structured data, this crate decides to combine both these concepts into one.

Variants

Mapping(Vec<(Node, Node)>)

Represents an associative container, where each key is unique in the association and mapped to exactly one value.

See https://yaml.org/spec/1.2.2/#10111-generic-mapping

Sequence(Vec<Node>)

Represents a collection indexed by sequential integers starting with zero.

See https://yaml.org/spec/1.2.2/#10112-generic-sequence

String(String)

Represents a Unicode string, a sequence of zero or more Unicode characters.

See https://yaml.org/spec/1.2.2/#0113-generic-string

Null

Represents the lack of a value.

See https://yaml.org/spec/1.2.2/#10211-null

Boolean(bool)

Represents a true/false value.

See https://yaml.org/spec/1.2.2/#10212-boolean

Integer(i64)

Represents arbitrary sized finite mathematical integers.

See https://yaml.org/spec/1.2.2/#10213-integer

FloatingPoint(String)

Represents an approximation to real numbers.

See https://yaml.org/spec/1.2.2/#10214-floating-point
