Struct RoleDefinition 

pub struct RoleDefinition {
    pub name: String,
    pub description: Option<String>,
    pub scopes: Vec<String>,
}

Role definition for field-level RBAC.

Defines which GraphQL scopes a role grants access to. Used by the runtime to determine which fields a user can access based on their assigned roles.

Example

{
  "name": "admin",
  "description": "Administrator with all scopes",
  "scopes": ["admin:*"]
}

Fields

name: String

Role name (e.g., “admin”, “user”, “viewer”).

description: Option<String>

Optional role description for documentation.

scopes: Vec<String>

List of scopes this role grants access to. Scopes follow the format: action:resource (e.g., “read:User.email”, “admin:*”)

Implementations

impl RoleDefinition

pub fn new(name: String, scopes: Vec<String>) -> Self

Create a new role definition.

pub fn with_description(self, description: String) -> Self

Add a description to the role.

pub fn has_scope(&self, required_scope: &str) -> bool

Check if this role has a specific scope.

Supports exact matching and wildcard patterns:

• read:User.email matches exactly
• read:* matches any scope starting with “read:”
• read:User.* matches “read:User.email”, “read:User.name”, etc.
• admin:* matches any admin scope

Trait Implementations

impl Clone for RoleDefinition

fn clone(&self) -> RoleDefinition

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RoleDefinition

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for RoleDefinition

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for RoleDefinition

fn eq(&self, other: &RoleDefinition) -> 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.

impl Serialize for RoleDefinition

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
