Struct Limits 

pub struct Limits {
    pub request_bytes: Option<usize>,
    pub object_bytes: Option<usize>,
    pub walk_bytes: Option<usize>,
}

The ceilings one connection serves under.

Every field defaults to Some. See the module docs for why that is the whole point.

Fields

request_bytes: Option<usize>

Bytes of pkt-line payload gunnar will hold for one request before it refuses. None removes the ceiling.

object_bytes: Option<usize>

Bytes of a single object gunnar will put in a pack. None removes the ceiling.

walk_bytes: Option<usize>

Bytes of object bookkeeping one traversal may hold. None removes the ceiling.

Charged at WALK_BYTES_PER_OBJECT against the ids live in the walk, which is not the same as the ids it has emitted — see crate::DEFAULT_BUDGET for the three separate accumulators the object count used to charge and the fourth it charged not at all.

Implementations

impl Limits

pub fn new() -> Self

The defaults — both ceilings on.

pub fn request_bytes(self, limit: usize) -> Self

Cap the bytes held for one peer-supplied request.

pub fn object_bytes(self, limit: usize) -> Self

Cap a single object’s size.

pub fn walk_bytes(self, limit: usize) -> Self

Cap the object bookkeeping one traversal may hold.

pub fn no_alloc_limit(self) -> Self

Remove all the ceilings entirely.

Only for a peer whose bytes are trusted and a repository whose contents are known: a local gunnar mirror between two directories on the same box, or a benchmark that is measuring what the ceiling costs. Never on a path that answers the network. Both sizes this guards are chosen by somebody other than the server — one by the peer framing the request, one by whoever pushed the object — which is the same reason gunnar_pack::IndexOptions::no_alloc_limit carries the same warning.
