MSRV Policy

The MSRV (Minimum Supported Rust [toolchain] Version) policy of my crates for a [semver-compatible bump] is the following:

stable - 9

More precisely:

• Patch[^patch] bump ⇒ same MSRV

Question

HI!

Question and idea about narrowing lifetime of mutable references.

In rust code when developing finite state machines, behaviour trees and other algorithms we often need to pass around Context on which these algorithms will work.

Understanding the role of SONAME in dynamic linkage and dynamic loading

Note that this is a Linux-specific feature.

The primary role of SONAME

Say we are a library libfoo.so.3.5, and some dependent binary artifact is being linked against us.

• Note that this dependent binary artifact may well be a final executable, à la ./main;
