Documentation

Overview

Package ptr provides utilities for pointer operations using storage layer paths.

Index

• func Ptr(data interface{}, path storage.Path) (interface{}, error)
• func ValidateASTArrayIndex(arr *ast.Array, s string, path storage.Path) (int, error)
• func ValidateArrayIndex(arr []interface{}, s string, path storage.Path) (int, error)
• func ValidateArrayIndexForWrite(arr []interface{}, s string, i int, path storage.Path) (int, error)
• func ValuePtr(data ast.Value, path storage.Path) (ast.Value, error)

Functions

func Ptr

func Ptr(data interface{}, path storage.Path) (interface{}, error)

func ValidateASTArrayIndex

func ValidateASTArrayIndex(arr *ast.Array, s string, path storage.Path) (int, error)

func ValidateArrayIndex

func ValidateArrayIndex(arr []interface{}, s string, path storage.Path) (int, error)

func ValidateArrayIndexForWrite

func ValidateArrayIndexForWrite(arr []interface{}, s string, i int, path storage.Path) (int, error)

ValidateArrayIndexForWrite also checks that `s` is a valid way to address an array element like `ValidateArrayIndex`, but returns a `resource_conflict` error if it is not.

func ValuePtr

func ValuePtr(data ast.Value, path storage.Path) (ast.Value, error)
