Struct Permissions 

pub struct Permissions {
    pub subject_name: String,
    pub default: Decision,
    pub rules: Vec<Rule>,
}

Subject-specific permissions block (Spec §7.3).

Fields

subject_name: String

Subject name (corresponds to the DDS-Security identity-certificate DN or the REST API key owner).

default: Decision

Default decision when no rule matches.

rules: Vec<Rule>

List of rules in order.

Implementations

impl Permissions

pub fn evaluate(&self, op: Operation, topic: &str) -> Decision

Returns the decision for a concrete operation on a topic. Spec §7.3 decision tree:

1. First matching rule with effect = Deny -> Deny.
2. First matching rule with effect = Permit -> Permit.
3. Otherwise default.

Trait Implementations

impl Clone for Permissions

fn clone(&self) -> Permissions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Permissions

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

Formats the value using the given formatter.

impl Default for Permissions

fn default() -> Permissions

Returns the “default value” for a type.

impl Eq for Permissions

impl PartialEq for Permissions

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
