Enum SendLayout 

pub enum SendLayout {
    Compact,
    Fast,
    Packed,
    Smallest,
    Redundant,
}

The wire LAYOUT a Send modifier picks — the size↔speed dial the sender chooses for their link. The transpiler maps this to the runtime’s numeric codec. The sender knows their use case; this lets them express it in one word.

Variants

Compact

compact / small — smallest wire (LEB128 varint). For a bandwidth-bound link (mobile, WAN, metered). This is also the default when no layout word is given.

Fast

fast / quickly — fastest decode (fixed-width memcpy, zero parse). For a latency-bound / fat link (LAN, datacenter, RDMA).

Packed

packed — varint size with SIMD group-varint decode; the balanced middle.

Smallest

smallest / best — turn on the per-column compression menu (delta / delta-of-delta / frame-of-reference / run-length / dictionary), auto-selecting each column’s smallest form and never exceeding plain varint. For a bandwidth-bound link where CPU is cheap relative to bytes.

Redundant

redundant / tough — forward error correction: the message is split into Reed-Solomon shards and each is published as its own packet, so a receiver reconstructs the exact message from any K even after some are lost. For a lossy / one-way link (UDP, multicast, BLE, LoRa) where retransmit is impossible.

Trait Implementations

impl Clone for SendLayout

fn clone(&self) -> SendLayout

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SendLayout

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

Formats the value using the given formatter.

impl Hash for SendLayout

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for SendLayout

fn eq(&self, other: &SendLayout) -> 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.
