Starting version 0.9.19, cargo-nextest has update functionality built-in. Simply run
cargo nextest self update to check for and perform updates.
The nextest updater downloads and installs the latest version of the cargo-nextest binary from get.nexte.st.
To request a specific version, run (e.g.)
cargo nextest self update --version 0.9.19.
For older versions
If you're on cargo-nextest 0.9.18 or below, update by redownloading and reinstalling the binary following the instructions at Pre-built binaries.
cargo-nextest 0.9.21 and above has a new
default-no-update feature, which will contain all default features except for self-update. The recommended, forward-compatible way to build cargo-nextest is with
--no-default-features --features default-no-update.
