Struct BlobFetchParams 

pub struct BlobFetchParams {
    pub ticket: String,
    pub dest_path: String,
    pub from: Vec<String>,
}

Params of Request::BlobFetch: the mcpmesh/blob/1 ticket and the LOCAL export path.

Fields

ticket: String

dest_path: String

from: Vec<String>

ADDITIONAL sources to try if the ticket’s publisher does not answer (#83). api_minor >= 47.

Content addressing makes every recipient a potential source, and without this the control API made that unusable: a ticket names ONE address, so a file shared with a room became unfetchable the moment the sender closed their laptop — even though other people in the room already held the identical, verified bytes.

Each entry is a stable principal (eid: device, b64u: user_id) or a paired nickname — the same vocabulary open_session takes. They are preferred in order, after the ticket’s own address, so the publisher stays the first choice and a live one costs nothing — alternates are not dialled at all when it answers.

Since 0.49.1 the dials are hedged: an alternate starts about a second after a source has failed to answer, rather than after that source’s full dial timeout. A source unreachable at the head of the list therefore costs about a second, not twenty, and a long from list is no longer a long wait. Each source is still dialled at most once.

An alternate only works if it can serve you. The bytes are BLAKE3-verified against the ticket’s hash whoever supplies them, so a hostile alternate cannot substitute content — but it must have republished the hash into a scope that grants you, or it answers with a permission refusal and the fetch moves on. Every failure mode falls through, not only an unreachable dial: a refusal, a missing hash, a mid-stream reset, and a stalled transfer all move to the next source.

Additive: absent from an older caller’s payload and read as empty, which is the single-source behaviour. Capped at MAX_BLOB_SOURCES; more is an error rather than a silent truncation.
