Struct IndexReadOptions 

pub struct IndexReadOptions {
    pub max_checkpoints: usize,
    pub max_window_bytes: u64,
    pub max_window_payload_bytes: usize,
}

Allocation limits applied while parsing an untrusted index file.

The defaults permit more than four million checkpoints while preventing a small hostile header from requesting an effectively unbounded allocation. Applications opening exceptionally large trusted indexes can raise these limits explicitly with the read_*_with_options methods.

Fields

max_checkpoints: usize

Maximum number of checkpoint records.

max_window_bytes: u64

Maximum sum of stored predecessor-window payload bytes.

max_window_payload_bytes: usize

Maximum bytes in one stored predecessor-window payload.
