Struct CStringVec

pub struct CStringVec { /* private fields */ }

Used to simulate an array of C-style strings.

Implementations

impl CStringVec

pub fn new(strings: &[&str]) -> Result<Self, Error>

Creates a new C string vector from the provided rust strings.

C strings are continuous byte regions that end in \0 and do not contain \0 anywhere else.

Use as_c_array to get an unowned raw pointer to the array, to pass into FFI C code.

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

Returns the underlying array of C strings as a C array pointer. The array must not change after construction to ensure that this pointer remains valid.

pub fn len(&self) -> usize

Returns the number of elements in the vector.

pub fn is_empty(&self) -> bool

Returns whether the vector is empty.

Trait Implementations

impl Debug for CStringVec

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
