* Similarly rename `installCargoTargetDirHook` to `installCargoArtifactsHook` * The intention is to highlight that "install" implies "copy to output" and not anywhere else * Also avoids the potential confusion of "cargo target dir" (location of cargo's artifacts) with "cargo target" (which is the target architecture/platform we want cargo to build for)

$cargoBuildLog is either undefined or does not point to a valid file location!
|
|
By default `buildPackage` will capture cargo's output and use it to determine which binaries
|
|
should be installed (instead of just guessing based on what is present in cargo's target directory).
|
|
If you are overriding the derivation with a custom build step, you have two options:
|
|
1. override `installPhaseCommand` with the appropriate installation steps
|
|
2. ensure that cargo's build log is captured in a file and point $cargoBuildLog at it
|
|
At a minimum, the latter option can be achieved with running:
|
|
cargoBuildLog=$(mktemp cargoBuildLogXXXX.json)
|
|
cargo build --message-format json-render-diagnostics >"$cargoBuildLog"
|
|
''}
