Struct `CStringArray`

pub struct CStringArray { pub(in ::sys::process::unix::common::cstring_array) ptrs: Vec<*const c_char> }

Helper type to manage ownership of the strings within a C-style array.

This type manages an array of C-string pointers terminated by a null pointer. The pointer to the array (as returned by as_ptr) can be used as a value of argv or environ.

Fields

ptrs: Vec<*const c_char>

Implementations

`impl CStringArray`

fn with_capacity(capacity: usize) -> Self: Creates a new CStringArray with enough capacity to hold capacity strings.
fn write(&mut self, index: usize, item: CString): Replace the string at position index.
fn push(&mut self, item: CString): Push an additional string to the array.
fn as_ptr(&self) -> *const *const c_char: Returns a pointer to the C-string array managed by this type.
fn iter(&self) -> CStringIter<'_>: Returns an iterator over all CStrs contained in this array.
