Struct ModuleAllocations 

pub struct ModuleAllocations {
    pub functions: Box<[FunctionEntry]>,
    pub arg_info: Box<[Box<[ArgInfo]>]>,
    pub name: CString,
    pub version: CString,
}

The heap allocations a ModuleEntry points into.

A C extension puts its zend_function_entry[], name and version in .rodata, so the linker owns them for the life of the process. ext-php-rs builds them at MINIT from an arbitrary #[php_module] body, so this struct owns them instead, stored inside the extension’s own StaticModuleEntry.

None of it can be freed. module_destructor walks module->functions reading fname after MSHUTDOWN for dl()-loaded modules, get_extension_funcs() walks it during a request, and zend_register_functions keeps zend_internal_function.arg_info pointing into arg_info for the whole process.

Fields

functions: Box<[FunctionEntry]>

The module’s function table, NUL-terminated.

arg_info: Box<[Box<[ArgInfo]>]>

Argument info of each module function, one table per function.

name: CString

The module name handed to PHP.

version: CString

The module version handed to PHP.
