Struct Frame 

pub struct Frame {
    pub granted: Vec<Capability>,
    pub provided: Vec<Provided>,
    pub withheld: Vec<Capability>,
}

A hold as an artifact names it.

Fields

granted: Vec<Capability>

Host capabilities granted from the host.

provided: Vec<Provided>

The pure providers standing in for host capabilities, each for the whole program or, under for, for the packages it names.

withheld: Vec<Capability>

Host capabilities neither granted nor provided: a call is a breach.

Implementations

impl Frame

pub fn block(&self, host_io: u64) -> Value

The receipt’s frame block: {"granted":[…],"withheld":[…],"host_io":n}.

pub fn provided_json(&self) -> Value

The providers as the lock records them: the provider, its settings, and for with the packages it serves when it is scoped.

pub fn to_json(&self) -> Value

The hold as a crash trace writes it.

pub fn from_json(j: &Value) -> Result<Frame, String>

Read a hold back.

Errors

When a list is missing, a label names no host capability, or a provider does not parse.

pub fn withheld_names(&self) -> Vec<(&'static str, Capability)>

Every host name the hold withholds, with its capability.
