Struct TransferConfig 

pub struct TransferConfig {
    pub concurrency: usize,
    pub max_attempts: u32,
    pub initial_backoff: Duration,
    pub backoff_max: Duration,
    pub url_rewriter: Option<UrlRewriter>,
    pub upload_url_rewriter: Option<UrlRewriter>,
    pub batch_size: usize,
    pub detect_content_type: bool,
}

Tunables for the transfer queue.

Defaults aim at “sensible for a developer laptop on a corporate VPN”: not too aggressive on concurrency, generous retries for flaky links. Upstream Git LFS scales concurrency to CPU count; this crate hard-codes 8 and lets callers override.

Fields

concurrency: usize

Max number of concurrent in-flight transfers.

max_attempts: u32

Total attempts per object, including the first.

9 means “try once, then up to 8 retries”. Matches upstream’s defaultMaxRetries = 8 (upstream counts retries; we count attempts, hence +1).

initial_backoff: Duration

Sleep before the first retry. Doubled before each subsequent retry, capped at backoff_max.

backoff_max: Duration

Upper bound for exponential backoff between retries.

url_rewriter: Option<UrlRewriter>

Optional rewriter applied to download action URLs before transfer. Carries url.<base>.insteadOf when lfs.transfer.enablehrefrewrite=true. None ⇒ no rewriting.

upload_url_rewriter: Option<UrlRewriter>

Optional rewriter applied to upload + verify action URLs. Carries url.<base>.pushInsteadOf (falling back to insteadOf) when lfs.transfer.enablehrefrewrite=true. None ⇒ no push-direction rewriting, in which case the upload-side falls back to url_rewriter.

batch_size: usize

Max objects per POST /objects/batch call. The transfer queue chunks the input list into runs of this size and issues one batch API call per chunk. Default: 100 (matches upstream’s lfs.transfer.batchSize default). Values < 1 are clamped to 1.

detect_content_type: bool

lfs.<url>.contenttype — when true (default), the basic upload adapter sniffs the first 512 bytes of each object and sets the Content-Type header on the action PUT to the detected MIME type. When false, the adapter sends application/octet-stream so a misconfigured CDN can’t reject the upload based on its content sniffing. Honored only when the batch response didn’t already set a Content-Type in action.header.
