Struct ffi_pool::CStringPool

pub struct CStringPool { /* fields omitted */ }

A thread-safe pool of CStrings which can be readily reused with strs for ease of FFI interactions.

Methods

impl CStringPool

fn new(default_string_capacity: usize) -> CStringPool

Create a new pool with a given default capacity for newly allocated CStrings.

fn with_capacity(
    pool_capacity: usize,
    default_string_capacity: usize
) -> CStringPool

Create a new pool with an additional maximum capacity. Allocating new CStrings when the pool is at capacity will block until a new CString is available.

fn get_str<T: AsRef<str>>(&self, s: T) -> Result<Item<CString>, NulError>

Allocate a new CString from the pool. This will check the supplied str for interior nul bytes.

fn get_c_str<T: AsRef<CStr>>(&self, s: T) -> Item<CString>

Allocate a new CString from the pool, using a CStr as a source.

impl Clone for CStringPool
