Struct CPPArray

#[repr(C)]
pub struct CPPArray<T> {
    pub len: usize,
    pub ptr: *const T,
}

Array for FFI purposes between C++ and Rust. If len is 0, ptr is allowed to be nullptr, otherwise, ptr must be valid.

Fields

len: usize

Number of elements in the array

ptr: *const T

Pointer to the first element in the array, may be null in the case of a 0 length array, but is not guaranteed to always be null of len is 0.

Implementations

impl CPPArray<u8>

pub unsafe fn as_utf8_str(&self) -> &str

Safety

input must refer to a valid string, sized according to len. A valid string consists of UTF-8 characters. The caller is responsible for ensuring the byte sequence consists of valid UTF-8 characters.

Trait Implementations

impl<T> From<&Vec<T>> for CPPArray<T>

fn from(value: &Vec<T>) -> Self

Converts to this type from the input type.

impl From<&str> for CPPArray<u8>

fn from(value: &str) -> Self

Converts to this type from the input type.

impl From<Option<&str>> for CPPArray<u8>

fn from(value: Option<&str>) -> Self

Converts to this type from the input type.
