Enum Origin 

pub enum Origin {
    BuiltIn,
    Configuration,
    UserPolicy,
    MachinePolicy,
}

Where a layer came from, in order of authority.

Machine policy wins over user policy, which wins over the user’s own configuration, which wins over what this build ships.

Variants

BuiltIn

What this build ships when nothing else says otherwise.

Configuration

The user’s own settings. The only layer Layer::user_may_extend gates.

UserPolicy

Policy applied to this user, and administered rather than chosen.

MachinePolicy

Policy applied to this machine. Nothing overrides it.

Implementations

impl Origin

pub fn is_managed(self) -> bool

Whether a layer from here is administered rather than chosen, which is what the interface indicates so that a refusal reads as a decision somebody made rather than as the application being unpredictable.

Trait Implementations

impl Clone for Origin

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Origin

impl Debug for Origin

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

Formats the value using the given formatter.

impl Display for Origin

The name a person knows a layer by, which is the vocabulary concept 10 uses and the vocabulary the shipped policy file and the manual page use with it.

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

Formats the value using the given formatter.

impl Eq for Origin

impl Ord for Origin

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.

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

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

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 Origin

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Origin

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

This method returns an ordering between self and other values if one exists.

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

Tests greater than (for self and other) and is used by the > operator.

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

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