Struct ReadLimit 

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

A checked read length in bytes: positive and at most ReadLimit::MAX, the in-memory snapshot cap.

Implementations

impl ReadLimit

pub const MAX: u64

Largest window one snapshot may allocate (256 MiB).

pub const DEFAULT_TAIL: Self

The default tail window (256 KiB), also follow’s initial window.

pub fn new(value: u64) -> Result<Self, ReadLimitError>

Admit one length; zero and anything above ReadLimit::MAX are refused before any transfer or allocation.

pub const fn get(self) -> u64
