std/integ ​

Supplementer package for Integrated Jule. Provides helper API to make interoperability easy and defines standards for common operations.

INFO

This packages includes some built-in powered functions:

Index ​

fn AnyToUnsafeptr(x: any): *unsafe
fn UTF16FromString(mut s: string): []u16
fn UTF16ToString(s: []u16): string
fn UTF16PtrToString(s: *u16): string
fn BytePtrToString(s: *byte): string
fn BytesFromString(s: string): []byte

AnyToUnsafeptr ​

jule
fn AnyToUnsafeptr(x: any): *unsafe

Returns unsafe pointer to the allocation of the type any. It may be handled like C's voidptr type. It does not ensure safety of the allocation, so x may be deallocated while memory pointer is still alive. Make sure the allocation will not be deallocated until unsafe pointer being unreachable, otherwise any memory access may lead SEGFAULT.

UTF16FromString ​

jule
fn UTF16FromString(mut s: string): []u16

Returns the UTF-16 encoding of the UTF-8 string s, with a terminating NULL added. If s includes NULL character at any location, ignores followed characters.

UTF16ToString ​

jule
fn UTF16ToString(s: []u16): string

Returns the UTF-8 encoding of the UTF-16 sequence s, with a terminating NULL removed. Returns empty string if s is nil.

UTF16PtrToString ​

jule
fn UTF16PtrToString(s: *u16): string

Returns the UTF-8 encoding of the UTF-16 sequence s in *u16 form, with a terminating NULL removed. Returns empty string if s is nil.

BytePtrToString ​

jule
#disable boundary
fn BytePtrToString(s: *byte): string

Returns the string of s, with a terminating NULL removed. Returns empty string if pointer is nil.

BytesFromString ​

jule
fn BytesFromString(s: string): []byte

Returns s as NULL terminated byte slice which is able to be used safely as NULL terminated string pointer. If s contains NULL termination at any location, accepts NULL termination is the end of s and skips following bytes.
