Trait ext_php_rs::binary::Pack
source · pub unsafe trait Pack: Clone {
// Required methods
fn pack_into(vec: Vec<Self>) -> *mut zend_string;
fn unpack_into(s: &zend_string) -> Vec<Self>;
}Expand description
Used to convert between Zend binary strings and vectors. Useful in
conjunction with the pack and unpack functions built-in to PHP.
§Safety
The types cannot be ensured between PHP and Rust, as the data is represented as a string when crossing the language boundary. Exercise caution when using these functions.
Required Methods§
sourcefn pack_into(vec: Vec<Self>) -> *mut zend_string
fn pack_into(vec: Vec<Self>) -> *mut zend_string
sourcefn unpack_into(s: &zend_string) -> Vec<Self>
fn unpack_into(s: &zend_string) -> Vec<Self>
Unpacks a given Zend binary string into a Rust vector. Can be used to
pass data from pack in PHP to Rust without encoding into another
format. Note that the data must be all one type, as this
implementation only unpacks one type.
§Safety
There is no way to tell if the data stored in the string is actually of
the given type. The results of this function can also differ from
platform-to-platform due to the different representation of some
types on different platforms. Consult the pack function
documentation for more details.
§Parameters
s- The Zend string containing the binary data.
