The XMODEM protocol in Rust
This is derived from https://github.com/awelkie/xmodem.rs. It has been modified
primarily to support no_std use and for use with the 2018 edition. All four
permutations of standard 128-byte and 1024-byte block sizes, classic and CRC16
variants are supported for send and receive. YMODEM and ZMODEM are not
implemented. In addition, the send and recv methods return the number of
bytes of data sent or received.
For a no_std build, it is necessary to request the core feature in addition
to --no-default-features or default-features = false on account of
cargo#1839. Additionally, your compiler must be known to core_io. Changes
are welcome to allow the use of alternate crates providing Read and Write
traits with the same signatures as those in std::io; unfortunately this does
not include (most of?) the Embedded HAL crates, which provide slightly different
signatures.
The tests require the binaries found in the lrzsz package. There are no tests
for the no_std build.
