pub struct DownloaderConfig {
    pub abr_settings: AbrSettings,

Configuration for Downloader.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

abr_settings: AbrSettings

Settings for the shared ABR controller owned by the Downloader.

cancel: CancellationToken

Cancellation token — when cancelled, the download loop exits.

demand_throttle: Duration

Throttle delay for demand (low-priority) processing. Gives urgent work a chance to preempt before demand batch runs.

soft_timeout: Duration

Soft timeout. When a fetch has not produced a response within this duration, the Downloader publishes DownloaderEvent::LoadSlow on the peer’s bus (if any). The request itself is not aborted — it keeps running until hard timeout fires.

client: HttpClient

HTTP client used for all fetches. Cloned by the Downloader to share the underlying reqwest::Client (and its connection pool) with the caller. Pass a single shared HttpClient to multiple Downloaders to share keep-alive sockets across them.

runtime: Option<Handle>

Tokio runtime handle for the download loop.

• Some(handle) — the loop runs as a task on this runtime.
• None — spawns as a task on the current runtime via task::spawn.

max_concurrent: usize

Maximum number of concurrent in-flight fetch commands.

Implementations

impl DownloaderConfig

pub fn builder() -> DownloaderConfigBuilder

Create an instance of DownloaderConfig using the builder syntax

impl DownloaderConfig

pub fn for_client(client: HttpClient) -> DownloaderConfigBuilder<SetClient>

Start a builder with client already set. Mirrors the ResourceConfig::for_src / HlsConfig::for_url pattern — the one required field is pre-supplied so callers can chain only the optional knobs they care about.

Trait Implementations

impl Clone for DownloaderConfig

fn clone(&self) -> DownloaderConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.
