Enum Setup 

pub enum Setup {
    Defs(Vec<CgroupDef>),
    Factory(fn(&Ctx<'_>) -> Vec<CgroupDef>),
}

How to produce the CgroupDefs for a step’s setup phase.

Construct via Setup::Defs(vec) (variant constructor for a static list), Setup::with_factory (runtime-generated from &Ctx), Setup::default() (no cgroups — Setup::Defs(Vec::new())), or via From<Vec<CgroupDef>> (vec![def1, def2].into()).

Variants

Defs(Vec<CgroupDef>)

Static list of cgroup definitions.

Factory(fn(&Ctx<'_>) -> Vec<CgroupDef>)

Factory that generates definitions from the runtime context.

Implementations

impl Setup

pub const fn with_factory(f: fn(&Ctx<'_>) -> Vec<CgroupDef>) -> Self

Construct a Setup::Factory from a function pointer. with_factory per the scenario-module builder convention (with_X = constructor variant; see the module-level docs on crate::scenario). The Defs variant is constructed directly via Setup::Defs(vec) (variant constructor) or Default::default() for the empty case; Factory needs a named constructor because variant construction with a fn pointer literal is awkward to read.

Trait Implementations

impl Clone for Setup

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Setup

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Setup

fn default() -> Self

Empty Setup::Defs — no cgroups created. The Factory variant cannot serve as a Default because it holds a fn pointer with no semantic no-op.

impl From<Vec<CgroupDef>> for Setup

fn from(defs: Vec<CgroupDef>) -> Self

Converts to this type from the input type.
