Struct PathList 

pub struct PathList {
    pub base: Vec<String>,
    pub extra: Vec<String>,
    pub replace: bool,
}

A configurable path list with extend-by-default semantics: resolve() returns base ∪ extra unless replace is set, in which case only extra is used. This lets config widen a security-relevant list (add a read path) safely, while shrinking one (dropping a loader path that would break confinement) requires an explicit replace = true opt-in. A widening is surfaced via PathList::widens so it can be disclosed (never silent).

Fields

base: Vec<String>

Built-in defaults (today’s constant). Not normally set from config.

extra: Vec<String>

Operator additions (extend) — or the full set when replace.

replace: bool

true ⇒ ignore base, use only extra (the shrink opt-in).

Implementations

impl PathList

pub fn from_defaults(base: &[&str]) -> PathList

A default-backed list from a static slice (the const-mirroring constructor).

pub fn resolve(&self) -> Vec<String>

The effective list: base ∪ extra (dedup, order-preserving), or extra alone when replace.

pub fn widens(&self) -> bool

true when the operator has widened the built-in list (added entries without replacing) — a disclosure-worthy loosening.
