Struct Spec 

pub struct Spec<'a> {
    pub package: &'a str,
    pub manifest: &'a str,
    pub catalog: &'a str,
    pub crate_name: &'a str,
    pub kfuncs: Vec<Kfunc>,
    pub ksyms: &'a [(&'a CStr, u8, u32)],
    pub variants: &'a [(&'a str, bool)],
}

What a Rust BPF scheduler hands the build: where its BPF crate is, what it calls and reads from the kernel, and the object variants to build.

Fields

package: &'a str

The package, for the warning on a host without the toolchain.

manifest: &'a str

The BPF crate’s manifest, catalog and binary name.

catalog: &'a str

crate_name: &'a str

kfuncs: Vec<Kfunc>

ksyms: &'a [(&'a CStr, u8, u32)]

Per-CPU kernel variables read as ksyms: the name, its type and the size. They are weak, since not every kernel has every one.

variants: &'a [(&'a str, bool)]

The objects to build, by name, and whether each is for a kernel whose scx_bpf_cid_topo() takes the structure’s size.
