Module avr_progmem::raw

Raw direct progmem access

This module provides functions to directly access the progmem, such as read_value.

It is recommended to use best-effort wrappers in wrapper and string, which use these functions internally. This is in particular, because having a raw static that is stored in the progmem is very hazardous since Rust does not understand the difference between the normal data memory domain and the program memory domain, and allows safe code to directly access those raw progmem statics, which is undefined behavior. The wrapper types in wrapper and string, prevent safe code from directly accessing these statics and only offer dedicated accessor methods that first load the data into the normal data memory domain via the function of this module.

Functions

read_byte^⚠

Read a single byte from the progmem.

read_value^⚠

Read a single T from progmem and return it by value.
