Struct TestConfig 

pub struct TestConfig {
    pub download_rounds: usize,
    pub upload_rounds: usize,
    pub stream_count: usize,
    pub sample_interval_ms: u64,
    pub ping_attempts: usize,
    pub upload_payload_bytes: usize,
    pub estimated_download_bytes: u64,

    pub http_retry_attempts: usize,

    pub http_retry_max_ms: u64,
}

Centralized test configuration for bandwidth measurement.

All timing, count, and sizing values used across the test pipeline are concentrated here so they can be tuned in one place.

Fields

download_rounds: usize

Number of download rounds per stream (each round fetches a different test file).

upload_rounds: usize

Number of upload rounds per stream (each round uploads a chunk of test data).

stream_count: usize

Number of concurrent streams in multi-stream mode.

sample_interval_ms: u64

Throttle interval for speed sampling in milliseconds (20 Hz max).

ping_attempts: usize

Number of ping attempts to measure latency, jitter, and packet loss.

upload_payload_bytes: usize

Payload size for each upload chunk in bytes.

estimated_download_bytes: u64

Estimated total download bytes for progress bar initialization.

estimated_upload_bytes: u64

Estimated total upload bytes for progress bar initialization.

latency_poll_interval_ms: u64

How often to poll latency under load (milliseconds).

http_retry_attempts: usize

Default number of HTTP retry attempts for transient failures.

http_retry_base_ms: u64

Initial HTTP retry backoff in milliseconds.

http_retry_max_ms: u64

Maximum HTTP retry backoff in milliseconds.

Implementations

impl TestConfig

pub fn stream_count_for(single: bool) -> usize

Get stream count based on single-connection mode.

pub fn retry_delay(attempt: usize) -> (u64, bool)

Calculate retry delay with exponential backoff. Returns (delay_ms, should_retry).

Trait Implementations

impl Clone for TestConfig

fn clone(&self) -> TestConfig

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TestConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for TestConfig

fn default() -> Self

Returns the “default value” for a type.
