Struct SystemChangeVecSlice 

#[repr(C)]
pub struct SystemChangeVecSlice {
    pub ptr: *const SystemChange,
    pub len: usize,
}

C-compatible slice type for $struct_name. This is a non-owning view into a Vec’s data.

Fields

ptr: *const SystemChange

len: usize

Implementations

impl SystemChangeVecSlice

pub const fn empty() -> Self

Creates an empty slice.

pub const fn len(&self) -> usize

Returns the number of elements in the slice.

pub const fn is_empty(&self) -> bool

Returns true if the slice is empty.

pub const fn as_ptr(&self) -> *const SystemChange

Returns a pointer to the slice’s data.

pub const fn as_slice(&self) -> &[SystemChange]

Converts the C-slice to a Rust slice.

pub fn get(&self, index: usize) -> Option<&SystemChange>

Returns a reference to the element at the given index, or None if out of bounds.

pub fn iter(&self) -> Iter<'_, SystemChange>

Returns an iterator over the elements.
