Struct Slice 

pub struct Slice {
    pub start: u32,
    pub len: u32,
}

A contiguous run in one of Plan’s pools.

Which pool is decided by the field that holds the slice, the same way a u32 reference is only meaningful in the arena it came from. A slice is Copy and eight bytes, so a node holding four of them is still a node that fits in a cache line.

Fields

start: u32

Index of the first element.

len: u32

Number of elements.

Implementations

impl Slice

pub const EMPTY: Self

The empty slice.

pub fn is_empty(self) -> bool

Whether the run has no elements.

pub fn range(self) -> Range<usize>

The run as a range, for indexing the pool it belongs to.
