# [−][src]Function core::ptr::slice_from_raw_parts

    pub fn slice_from_raw_parts<T>(data: *const T, len: usize) -> *const [T]

🔬 This is a nightly-only experimental API. (`slice_from_raw_parts` #36925)

recently added

Forms a slice from a pointer and a length.

The `len` argument is the number of elements, not the number of bytes.

# Examples

    #![feature(slice_from_raw_parts)]
    use std::ptr;

    // create a slice pointer when starting out with a pointer to the first element
    let mut x = [5, 6, 7];
    let ptr = &mut x[0] as *mut _;
    let slice = ptr::slice_from_raw_parts_mut(ptr, 3);
    assert_eq!(unsafe { &*slice }[2], 7);Run

## Search Tricks

Prefix searches with a type followed by a colon (e.g., `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g., `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g., `str,u8` or `String,struct:Vec,test`)
