Struct FileTransferConfig 

pub struct FileTransferConfig {
    pub chunk_size: usize,
    pub max_file_size: u64,
    pub max_concurrent_assemblies: usize,
    pub max_assemblies_per_sender: usize,
    pub max_total_buffered_bytes: u64,
}

File transfer configuration.

Fields

chunk_size: usize

Size of each chunk in bytes. Chunk sizes that would split a file into more chunks than the receive-side cap derived from max_file_size (one chunk per KiB of max_file_size, minimum 1024) are rejected by FileTransferManager::chunk_file — a receiver with the same configuration would drop every chunk of such a transfer.

max_file_size: u64

Maximum file size allowed (bytes).

max_concurrent_assemblies: usize

Maximum number of inbound files that may be reassembling at once. Chunks that would start an additional assembly are rejected; slots free when a transfer completes, is cancelled, or goes stale.

max_assemblies_per_sender: usize

Maximum number of inbound files a single sender may have reassembling at once, so one peer cannot occupy every assembly slot. Only as strong as sender authentication: MLS-path senders are cryptographically bound, but legacy plaintext senders are wire claims a peer can rotate — there, this quota bounds only honest peers, and the global count and byte caps are the real limits.

max_total_buffered_bytes: u64

Maximum total bytes buffered across all inbound assemblies. This — not the assembly counts — is the hard bound on receive-path memory. Each stored chunk is charged its payload plus a small fixed bookkeeping overhead, so floods of tiny chunks cannot pin more memory than the budget admits. Values below what a single max_file_size transfer charges are clamped up to it by FileTransferManager::with_config, or a maximum-size file could never complete.
