Struct ExecutionPolicy 

pub struct ExecutionPolicy { /* private fields */ }

What a run is permitted to run.

Implementations

impl ExecutionPolicy

pub fn deny_all() -> Self

The default: nothing may run.

pub fn allowing(self, execution: Execution) -> Self

The same policy with one more class permitted.

pub fn parse(names: &str) -> Result<Self, UnknownExecution>

The policy described by a comma-separated list of class names.

Errors

Returns the first name that is not a class, so that a typo in a permission is refused rather than quietly granting nothing.

pub fn permits(&self, execution: Execution) -> bool

Whether this class may run.

pub const fn permits_reading(&self, _reading: Reading) -> bool

Reading never needs permission; the method exists so that the two sides of the line are asked the same way and a caller cannot reach a source this build has not classified.

pub fn refusal(&self, execution: Execution) -> Option<Refusal>

What refusing this class means, or None if it is permitted.

pub fn permitted(&self) -> Vec<Execution>

The classes permitted, in a fixed order.
