Struct Map 

pub struct Map<'a> {
    body: &'a [u8],
    n: usize,
}

A zone map checked out, with its header validated once.

Fields

body: &'a [u8]

n: usize

Implementations

impl<'a> Map<'a>

pub fn open(file: &'a [u8]) -> Option<Map<'a>>

None for anything unreadable, which every caller must treat as “scan the block”.

fn key_at(&self, i: usize) -> u64

fn get(&self, key: u64) -> Option<Range>

Binary search over the packed entries by hand: the body is bytes, not Ranges, so slice::binary_search has nothing to search.
