Struct AllocatedLen 

pub struct AllocatedLen(/* private fields */);

The byte length of a live allocation.

Rust guarantees no allocation exceeds isize::MAX bytes, so a value read off a slice or a str carries that bound with it. A declared length read from a document is minted against the same bound, so every value of this type carries it however it arrived.

Implementations

impl AllocatedLen

pub fn new(bytes: u64) -> Option<Self>

A declared byte length, absent when it exceeds isize::MAX.

pub fn get(self) -> u64
