CountingPolicy

tor_proto::util::sink_blocker::counting_policy

Struct CountingPolicy 

Source 
pub(crate) struct CountingPolicy {
    remaining: Option<NonMaxU32>,
}
Expand description

A sink-blocking Policy that can allow a limited number of items to be sent.

This policy may be in three states:

  • Completely blocked
  • Completely unblocked: Able to send an unlimited number of items.
  • Will become blocked after a certain number of items are sent.

Fields§

§remaining: Option<NonMaxU32>

The number of items that may currently be sent.

None represents an unlimited number.

Implementations§

Source§

impl CountingPolicy

Source

pub(crate) fn new_unlimited() -> Self

Return a new unlimited CountingPolicy.

Source

pub(crate) fn new_blocked() -> Self

Return a new completely blocked CountingPolicy.

Source

pub(crate) fn new_limited(n: u32) -> Self

Return a new CountingPolicy that allows n items, and then becomes blocked.

§Limitations:

If n is greater than MAX_LIMIT, only MAX_LIMIT items will be allowed.

Source

fn saturating_add(&self, n: u32) -> Self

Return a new CountingPolicy that allows up to n more items to be sent than this one.

§Limitations:

If the total number of allowed items would be greater than MAX_LIMIT, only MAX_LIMIT items will be allowed.
