Function to_str

pub const fn to_str(this: &CStr) -> Result<&str, Utf8Error>

Converts this CStr to a string slice, excluding the nul terminator. Const equivalent of CStr::to_str

Performance

This function takes linear time to run, proportional to the length of this.

Const stabilization

The equivalent std function was const-stabilized in Rust 1.72.0.

Example

use konst::{ffi::cstr, unwrap_ctx};

use std::ffi::CStr;


const CS: &CStr = unwrap_ctx!(cstr::from_bytes_with_nul(b"of beads\0"));

const STRING: &str = unwrap_ctx!(cstr::to_str(CS));

assert_eq!(STRING, "of beads");
