pub unsafe fn read_f32_be(bytes: &[u8]) -> f32Expand description
Unsafe, near zero cost transmutation of a byte array slice into a 32-bit floating point using big-endianness.
§Safety
To make it “safe” and does not cause memory errors, you must ensure the input has at least 4 bytes prior to calling this.
§Arguments
bytes: the byte array reference
returns: f32
§Examples
use hyper_byte::read_f32_be;
let slice = [0u8; 16];
// PERFECTLY SAFE
let first_value = unsafe { read_f32_be(&slice[0..4]) };
// NOT SAFE
let second_value = unsafe { read_f32_be(&slice[9..9]) };
pub fn read_f32_safe_be(array: &[u8], index: &mut usize) -> f32 {
// "SAFE" because even if the array is not of this length,
// it will still at least panic and not cause undefined behaviour
let third_value = unsafe { read_f32_be(&array[*index..(*index+4)]) };
*index += 4;
third_value
}
