Struct CStringArray

pub struct CStringArray {
    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

pub fn with_capacity(capacity: usize) -> Self

Creates a new CStringArray with enough capacity to hold capacity strings.

pub fn write(&mut self, index: usize, item: CString)

Replace the string at position index.

pub fn push(&mut self, item: CString)

Push an additional string to the array.

pub fn as_ptr(&self) -> *const *const c_char

Returns a pointer to the C-string array managed by this type.

pub fn iter(&self) -> CStringIter<'_>

Returns an iterator over all CStrs contained in this array.
