Struct RetryConfig 

pub struct RetryConfig {
    pub max_attempts: u8,
    pub initial_backoff_ms: u64,
    pub max_backoff_ms: u64,
    pub reduce_chunk_on_retry: bool,
    pub min_sectors_per_read: u32,
}

Retry policy for idempotent read operations.

The policy is applied per failed read chunk/command and can combine capped exponential backoff with adaptive chunk-size reduction.

Fields

max_attempts: u8

Maximum attempts per operation, including the initial attempt. By default the value is 4.

Values below 1 are normalized by callers to at least one attempt.

initial_backoff_ms: u64

Initial backoff delay in milliseconds before the second attempt. First attempt is always immediate, so if there are no issues during reading, we don’t wait any time.

max_backoff_ms: u64

Upper bound for exponential backoff delay in milliseconds.

Each retry typically doubles the previous delay until this cap is reached.

reduce_chunk_on_retry: bool

Enable adaptive sector-count reduction on retry for READ CD operations.

Current implementation reduces chunk size from large reads toward smaller reads (for example 27 -> 8 -> 1) to have a higher change of success.

min_sectors_per_read: u32

Minimum sectors per READ CD command when adaptive reduction is enabled. Default value is 27 for 64KB per read.

Use 1 for maximal fault isolation; larger values can improve throughput.
