Struct ReceiveLimits 

pub struct ReceiveLimits {
    pub max_bytes: usize,
    pub max_depth: usize,
    pub max_elements: usize,
    pub max_string_bytes: usize,
    pub accept_computed: bool,
}

A receiver’s admission-control budget — the limits it will accept from a sender, so a malicious or buggy peer cannot exhaust the receiver’s memory, stack, or CPU. Enforced DURING decode, BEFORE the offending allocation or recursion happens, so an over-budget message is refused cleanly (the decode returns None) rather than processed. A receiver advertises these in the capability handshake so a cooperative sender stays within them; an uncooperative one is still bounded by the enforcement.

Fields

max_bytes: usize

Largest message body (post-decompress framing aside) the receiver will decode, in bytes.

max_depth: usize

Maximum container-nesting depth. Bounds decode RECURSION, so a deeply-nested but byte-small message cannot overflow the receiver’s stack (a remote crash).

max_elements: usize

Maximum element count for any single decoded collection (list / map / set / struct-list / numeric column). A claimed count above this is refused before the elements are read.

max_string_bytes: usize

Maximum byte length of any single decoded string.

accept_computed: bool

Whether to accept a SHIPPED computation (T_FUNC) at all. When false, a computed send is refused at decode — independent of (and prior to) the C2 acceptance contract that gates whether an accepted computation may be EVALUATED.

Trait Implementations

impl Clone for ReceiveLimits

fn clone(&self) -> ReceiveLimits

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ReceiveLimits

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ReceiveLimits

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for ReceiveLimits

fn eq(&self, other: &ReceiveLimits) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
