Struct Scope 

pub struct Scope { /* private fields */ }

One scope: an identity, a principal, and the grant it was opened under.

Read through super::Session::scope. It holds no balance: the balance is super::fold_balance over the ledger, decided inside the store for a reserve and read back from the log for everything else (super::Session::remaining). A number kept here would be a second answer to that question, and the wrong one on a stream more than one handle writes to. What the scope keeps of the grant is its words — the tag a refusal reports, the desc an audit reads.

Implementations

impl Scope

pub fn new(owner: String, grant: Option<BudgetGrant>) -> Self

Open a scope for owner with an optional grant, under a fresh kernel-issued id.

pub fn id(&self) -> &str

The kernel-issued scope id.

pub fn owner(&self) -> &str

Whose scope this is (a principal id, or super::ANON / super::SYSTEM).

pub fn grant(&self) -> Option<&BudgetGrant>

The grant this scope opened (or resumed) with, if any.

Trait Implementations
