crafter 0.3.1

//! ICMPv4 (`ICMP_*`) codepoint constants.
//!
//! Moved verbatim out of `icmp/constants.rs` into the `icmp/v4/` subtree;
//! nothing here changes wire behavior, defaults, or the public API surface.
//! These are re-exported at the `icmp` module root (via `v4/mod.rs` and
//! `icmp/mod.rs`), so every existing path — `crate::protocols::icmp::ICMP_*`,
//! the `protocols::mod.rs` re-exports, and the prelude — keeps resolving to the
//! same names. The version-specific `ICMPV6_*` constants stay in
//! `icmp/constants.rs`.
