Struct Grants 

pub struct Grants {
    pub filesystem: bool,
    pub process: bool,
    pub network: bool,
    pub environment: bool,
    pub session: bool,
}

What an extension may reach. The default grants everything, as pi does.

Fields

filesystem: bool

Read and write files.

process: bool

Run processes, which run as the user outside the sandbox.

network: bool

Send HTTP requests and resolve host names.

environment: bool

Read environment variables.

session: bool

Start turns and change the session and its files.

Implementations

impl Grants

pub fn none() -> Grants

Nothing outside the instance.

pub fn is_all(&self) -> bool

Whether every grant is given, as only all gives it.

pub fn covers(&self, capability: &str) -> bool

Whether these grants give all that capability, one of CAPABILITIES, does. False for any other name.

pub fn names(&self) -> Vec<&'static str>

The capabilities the grants amount to, as a manifest names them: all alone when they give everything, else each other one of CAPABILITIES they cover, then process when they let processes run, which no manifest grants without all. Empty for none.

pub fn parse(values: &[String]) -> Result<Grants, String>

The grants of manifest capabilities values, each one of CAPABILITIES or none. An empty list grants nothing, and only all grants running processes. Err names an unknown value, process, or none combined with another value.

pub fn union(self, other: Grants) -> Grants

What either self or other grants.

pub fn intersection(self, other: Grants) -> Grants

What both self and other grant.
