Enum Scope 

pub enum Scope {
    City,
    Building(Address),
    Workshop(Address),
}

What a halt, a release or an autonomy change applies to.

The wire form is what the histories already hold: city, building:<addr>, workshop:<addr>. The three words are here, the parse is here, and both ends of the ledger call this type, so a scope cannot be written one way and read another.

A word this build does not know is refused rather than read as some other scope: a city that read an unknown scope as its own would report itself shut, and one that read it as nothing would dispatch into a scope a person stopped.

Variants

City

Everything this city holds.

Building(Address)

One building and what is inside it.

Workshop(Address)

One workshop and what is inside it.

Implementations

impl Scope

pub fn covers(&self, addr: &Address) -> bool

Whether a standing decision on this scope reaches an address.

The city reaches everything; a building and a workshop reach what is within them, by the containment Address::is_within already decides, so “inside” means one thing in this city.

pub fn parse(raw: &str) -> Result<Scope, AxError>

Reads back what fmt::Display wrote.

Errors

E_WIRE_MISMATCH for a word that names none of the three shapes, and whatever Address::parse says about an address this city cannot hold.

Trait Implementations

impl Clone for Scope

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 Scope

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Scope

fn deserialize<D: Deserializer<'de>>(deserializer: D) -> Result<Self, D::Error>

impl Eq for Scope

impl Hash for Scope

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

impl Ord for Scope

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for Scope

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl PartialOrd for Scope

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool
