Module msg 

Safe, idiomatic wrappers for the CFE Message Services (CFE_MSG) API.

This module provides MessageRef and MessageMut structs to safely create, access, and modify the headers of CFE Software Bus messages. It operates on Rust byte slices (&[u8] and &mut [u8]) to prevent common errors associated with raw pointer manipulation.

Structs

CmdHeader

A Command Header.

MessageMut

A safe, writeable wrapper around a CFE message byte slice.

MessageRef

A safe, read-only wrapper around a CFE message byte slice.

MsgId

A type-safe, zero-cost wrapper for a cFE Software Bus Message ID.

TlmHeader

A Telemetry Header.

Enums

MsgType

The type of a cFE message (Command or Telemetry).

Functions

get_next_sequence_count

Gets the next sequence count value, handling rollovers correctly.

message_string_get

Copies a string from a fixed-size C-style char array within a message to a Rust buffer.

message_string_set

Copies a Rust string slice into a fixed-size C-style char array within a message.
