One launch’s inputs.

Fields

pkg_root: &'a Path

The package root as the entrypoint will see it.

lib_dirs: &'a [&'a str]

Library directories relative to pkg_root.

policy: HostLibsPolicy

store: &'a Path

Where the link farm and the recorded decision live. Created on demand; reused across launches of the same package on the same host.

ld_cache: &'a Path

The loader cache image describing the host.

icd_dirs: &'a [&'a str]

Directories of Vulkan ICD and EGL vendor files describing the host’s drivers. ICD_DIRS outside of tests.

extra_root: Option<&'a Path>

A fetched GL build’s extracted root, indexed ahead of the host: its GL_BUILD_LIB_DIRS and GL_BUILD_ICD_DIRS supply what the host could not.

set_roots: &'a [PathBuf]

Extracted roots of the dependency sets the package pins. Their libraries are the ones the bundle left out, so they are compared against the host exactly as a bundled copy would be.

host_libc: bool

Whether the launch can place host files over their bundled copies. Without that the host’s glibc is never chosen: the bundled executables’ run path would still find the bundled libc, and it cannot run under the host loader.
