Struct BackendAuthCapabilities 

pub struct BackendAuthCapabilities {
    pub mechanisms: Vec<AuthMechanism>,
    pub default: Option<usize>,
}

What the backend advertises at _info’s auth_capabilities field.

Per AUTHZ-S01-output §2. Backwards-compatible addition: clients that don’t know the field continue to ignore it.

Fields

mechanisms: Vec<AuthMechanism>

Mechanisms the backend supports. May be empty (no auth wired) but conventionally contains at least one entry; the framework default emits [Anonymous] when no backend has called DynamicHub::with_auth_capabilities.

default: Option<usize>

Index into mechanisms for the “primary” mechanism a generic client should try first. None means “no opinion; client chooses.”

Implementations

impl BackendAuthCapabilities

pub fn new( mechanisms: Vec<AuthMechanism>, default: Option<usize>, ) -> Result<Self, BackendAuthCapabilitiesError>

Construct a BackendAuthCapabilities, validating that default (if present) is in range.

pub fn anonymous_default() -> Self

The default value emitted by _info for backends that have not called DynamicHub::with_auth_capabilities: a single Anonymous mechanism, no preferred default.

This preserves today’s substrate behavior (anyone can call) while signaling “no auth wired” to capability-aware clients.

Trait Implementations

impl Clone for BackendAuthCapabilities

fn clone(&self) -> BackendAuthCapabilities

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BackendAuthCapabilities

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for BackendAuthCapabilities

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for BackendAuthCapabilities

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl PartialEq for BackendAuthCapabilities

fn eq(&self, other: &BackendAuthCapabilities) -> 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 BackendAuthCapabilities

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
