Struct RawCString 

pub struct RawCString { /* private fields */ }

A wrapper around the raw c_char pointer to a C string.

This is useful when you want to return a C string to JavaScript directly via NAPI-RS function without converting it to Rust string or performing any memory allocation.

The RawCString doesn’t implement FromNapiValue, so you can’t convert a JavaScript String to it.

Implementations

impl RawCString

pub fn new(inner: *const c_char, length: isize) -> Self

Create a new RawCString from a raw pointer and length.

If the inner string is null-terminated, you can pass `` as the length.

Trait Implementations

impl Debug for RawCString

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

Formats the value using the given formatter.

impl ToNapiValue for RawCString

unsafe fn to_napi_value(env: napi_env, val: Self) -> Result<napi_value>

Safety

fn into_unknown(self, env: &Env) -> Result<Unknown<'_>>
