Struct ffi_convert::CStringArray

#[repr(C)]
pub struct CStringArray {
    pub data: *const *const c_char,
    pub size: usize,
}

A utility type to represent arrays of string

Example

use ffi_convert::{CReprOf, CStringArray};
let pizza_names = vec!["Diavola".to_string(), "Margarita".to_string(), "Regina".to_string()];
let c_pizza_names = CStringArray::c_repr_of(pizza_names).expect("could not convert !");

Fields

data: *const *const c_char

Pointer to the first element of the array

size: usize

Number of elements in the array

Trait Implementations

impl AsRust<Vec<String, Global>> for CStringArray

fn as_rust(&self) -> Result<Vec<String>, AsRustError>

impl CDrop for CStringArray

fn do_drop(&mut self) -> Result<(), CDropError>

impl CReprOf<Vec<String, Global>> for CStringArray

impl RawPointerConverter<CStringArray> for CStringArray

fn into_raw_pointer(self) -> *const CStringArray

Creates a raw pointer from the value and leaks it, you should use Self::from_raw_pointer or Self::drop_raw_pointer to free the value when you’re done with it.

fn into_raw_pointer_mut(self) -> *mut CStringArray

Creates a mutable raw pointer from the value and leaks it, you should use Self::from_raw_pointer_mut or Self::drop_raw_pointer_mut to free the value when you’re done with it.

unsafe fn from_raw_pointer_mut( input: *mut CStringArray ) -> Result<CStringArray, UnexpectedNullPointerError>

Takes back control of a raw pointer created by Self::into_raw_pointer_mut.

unsafe fn from_raw_pointer( input: *const CStringArray ) -> Result<CStringArray, UnexpectedNullPointerError>

Takes back control of a raw pointer created by Self::into_raw_pointer.

unsafe fn drop_raw_pointer( input: *const T ) -> Result<(), UnexpectedNullPointerError>

Takes back control of a raw pointer created by Self::into_raw_pointer and drop it.

unsafe fn drop_raw_pointer_mut( input: *mut T ) -> Result<(), UnexpectedNullPointerError>

Takes back control of a raw pointer created by Self::into_raw_pointer_mut and drops it.
