Enum Dimension 

pub enum Dimension {
    Filesystem,
    Network,
    Exec,
}

The three trust dimensions an effect can touch. Kept deliberately small and fixed (design doc §7.2): every consequential effect a box can have on the world reduces to filesystem reach, network reach, or the ability to spawn arbitrary executables.

Variants

Filesystem

Network

Exec

Implementations

impl Dimension

pub const ALL: [Dimension; 3]

pub fn as_str(self) -> &'static str

impl Dimension

pub fn levels(self) -> &'static [Level]

The levels that carry a meaning on this dimension.

The vocabulary is shared across dimensions deliberately — it is small and the ordering is what matters — but sharing a vocabulary is not sharing a meaning. Loopback says nothing about a filesystem, and ReadWrite says nothing about a process. Accepting one anyway does not merely look untidy: it ranks, so it narrows, satisfies effect checks, and resolves to a sandbox — all while naming nothing.

pub fn permits_level(self, level: Level) -> bool

Does level mean anything on this dimension?
