anyhow 1.0.25

on Rust Cargo

Add no-std support (#53)

In no_std mode, the same API is almost all available and works the same way. To depend on Anyhow in no_std mode, disable our default enabled "std" feature in Cargo.toml. A global allocator is required.

[dependencies]
anyhow = { version = "1.0", default-features = false }

Since the ?-based error conversions would normally rely on the std::error::Error trait which is only available through std, no_std mode will require an explicit .map_err(Error::msg) when working with a non-Anyhow error type inside a function that returns Anyhow's error type.
