type Lexer struct {
	Input []rune
	// contains filtered or unexported fields
}

Lexer performs lexical analysis/scanning of the JSON

func NewLexer(input string) *Lexer

NewLexer creates and returns a pointer to the Lexer

func (l *Lexer) NextToken() model.Token

NextToken switches through the lexer's current char and creates a new model. It then it calls readChar to advance the lexer and it returns the token.

type Parser struct {
	// contains filtered or unexported fields
}

Parser holds a Lexer, errors, the currentToken, and the peekToken (next token). Parser methods handle iterating through tokens and building and AST.

func NewParser(l *Lexer) *Parser

New takes a Lexer, creates a Parser with that Lexer, sets the current token and the peek token and returns the Parser.

func (p *Parser) Errors() string

Errors is simply a helper function that returns the parser's errors

func (p *Parser) ParseValidation() (model.RootNode, error)

ParseValidation parses tokens and creates an AST. It returns the RootNode which holds a Value and in it the rest of the tree.
