Struct AccessTokenRequest 

pub struct AccessTokenRequest {
    pub client_id: Option<String>,
    pub grant_type: Option<GrantType>,
    pub audience: Option<String>,
    pub redirect_uri: Option<String>,
    pub client_nonce: Option<ByteString>,
    pub scope: Option<Scope>,
    pub ace_profile: Option<()>,
    pub req_cnf: Option<ProofOfPossessionKey>,
    pub issuer: Option<String>,
}

Request for an access token, sent from the client, as defined in section 5.8.1 of RFC 9200.

Use the AccessTokenRequestBuilder (which you can access using the AccessTokenRequest::builder() method) to create an instance of this struct.

Example

Figure 5 of RFC 9200 gives us an example of an access token request, given in CBOR diagnostic notation¹:

{
    "client_id" : "myclient",
    "audience" : "tempSensor4711"
}

This could be built and serialized as an AccessTokenRequest like so:

let request: AccessTokenRequest = AccessTokenRequest::builder()
   .client_id("myclient")
   .audience("tempSensor4711")
   .build()?;
let mut serialized = Vec::new();
request.clone().serialize_into(&mut serialized)?;
assert_eq!(AccessTokenRequest::deserialize_from(serialized.as_slice())?, request);

Fields

client_id: Option<String>

The client identifier as described in section 2.2 of RFC 6749.

grant_type: Option<GrantType>

Grant type used for this request.

Defaults to GrantType::ClientCredentials.

See also the documentation of GrantType for details.

audience: Option<String>

The logical name of the target service where the client intends to use the requested security token.

redirect_uri: Option<String>

URI to redirect the client to after authorization is complete.

client_nonce: Option<ByteString>

Client nonce to ensure the token is still fresh.

scope: Option<Scope>

Scope of the access request as described by section 3.3 of RFC 6749.

See also the documentation of Scope for details.

ace_profile: Option<()>

Included in the request if the AS shall include the ace_profile parameter in its response.

req_cnf: Option<ProofOfPossessionKey>

Contains information about the key the client would like to bind to the access token for proof-of-possession.

See also the documentation of ProofOfPossessionKey for details.

issuer: Option<String>

Issuer of the token. Note that this is only used by libdcaf and not present in the ACE-OAuth specification for access token requests. Instead, it is usually encoded as a claim in the access token itself.

Defined in section 3.1.1 of RFC 8392 and Table 6 of RFC 9200.

Implementations

impl AccessTokenRequest

pub fn builder() -> AccessTokenRequestBuilder

Initializes and returns a new AccessTokenRequestBuilder.

Trait Implementations

impl Clone for AccessTokenRequest

fn clone(&self) -> AccessTokenRequest

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AccessTokenRequest

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

Formats the value using the given formatter.

impl Default for AccessTokenRequest

fn default() -> AccessTokenRequest

Returns the “default value” for a type.

impl PartialEq for AccessTokenRequest

fn eq(&self, other: &AccessTokenRequest) -> 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 ToCborMap for AccessTokenRequest

fn serialize_into<W>(self, writer: W) -> Result<(), Error<W::Error>>

where Self: Sized, W: Write, W::Error: Debug,

Serializes this type as a CBOR map bytestring into the given writer.

fn deserialize_from<R>(reader: R) -> Result<Self, Error<R::Error>>

where Self: Sized, R: Read, R::Error: Debug,

Deserializes from the given reader — which is expected to be an instance of this type, represented as a CBOR map bytestring — into an instance of this type.

fn to_ciborium_value(&self) -> Value

Converts this type to a CBOR serializable Value using to_cbor_map.
