#[repr(C)]
pub struct FfiString {
    pub ptr: *const u8,
    pub len: usize,
}

Fields

ptr: *const u8

len: usize

Implementations

impl FfiString

pub fn from_string(s: String) -> Self

Create from Rust string. Caller must call ffi_free_string on the result.

pub fn from_str(s: &str) -> Self

Create from &str (copies). Caller must call ffi_free_string on the result.

pub fn to_string(self) -> String

Convert to Rust String. Consumes the FfiString (memory is freed).

pub fn empty() -> Self

Create empty FfiString (no allocation to free).
