Struct Invariant 

pub struct Invariant {
    pub scope: String,
    pub operation: String,
    pub resource_type: String,
    pub resource_id: String,
}

One executable authority invariant: (scope, operation, resourceType, resourceId).

The logical JSON form uses camelCase member names (resourceType, resourceId), matching the application-facing Context of Authority.

Fields

scope: String

The authority scope, e.g. documents:read:document-42.

operation: String

The operation the invariant permits.

resource_type: String

The resource type the operation applies to.

resource_id: String

The resource identifier, or "*" for the whole type.

Implementations

impl Invariant

pub fn new( scope: impl Into<String>, operation: impl Into<String>, resource_type: impl Into<String>, resource_id: impl Into<String>, ) -> Self

An invariant from its four normative elements, in normative order.

Trait Implementations

impl Clone for Invariant

fn clone(&self) -> Invariant

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Invariant

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Invariant

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for Invariant

impl From<&Invariant> for InvariantTuple

fn from(i: &Invariant) -> Self

Converts to this type from the input type.

impl Ord for Invariant

fn cmp(&self, other: &Invariant) -> 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.

impl PartialEq for Invariant

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Invariant

fn partial_cmp(&self, other: &Invariant) -> 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.

impl Serialize for Invariant

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
