Struct CsrAttrsResponse 

pub struct CsrAttrsResponse { /* private fields */ }

CSR Attributes response (RFC 7030 §4.5.2).

Contains a list of attribute OIDs that the EST server recommends or requires in client CSRs. This advertises support for:

• Post-quantum signature algorithms (ML-DSA)
• Post-quantum key encapsulation (ML-KEM)
• Composite algorithms (ML-DSA + traditional)
• Standard X.509 attributes

The response is a DER-encoded ASN.1 SEQUENCE of OIDs, base64-wrapped.

Implementations

impl CsrAttrsResponse

pub fn new(attributes: Vec<CsrAttribute>) -> Self

Creates a new CSR attributes response.

pub fn empty() -> Self

Creates an empty response (no attribute hints).

pub fn attributes(&self) -> &[CsrAttribute]

Returns the list of attributes.

pub fn add_attribute(&mut self, attr: CsrAttribute)

Adds an attribute to the response.

pub fn to_der(&mut self) -> &[u8]

Encodes the response as DER (ASN.1 SEQUENCE of OIDs).

This is a simplified DER encoder for the specific structure:

CsrAttrs ::= SEQUENCE OF AttrOrOID
AttrOrOID ::= OBJECT IDENTIFIER

Full ASN.1 encoding is delegated to the CA module.

pub fn to_base64(&mut self) -> String

Encodes the response as base64 for HTTP transport.

pub fn from_base64(base64_data: &str) -> EstResult<Self>

Decodes a base64-encoded CSR attributes response.

This is a simplified decoder that extracts OIDs from the DER structure. Full ASN.1 parsing is delegated to the CA module.

pub fn validate(&self) -> EstResult<()>

Validates the response structure.

pub fn builder() -> CsrAttrsBuilder

Builder: Starts a new response builder.

Trait Implementations

impl Clone for CsrAttrsResponse

fn clone(&self) -> CsrAttrsResponse

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CsrAttrsResponse

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CsrAttrsResponse

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for CsrAttrsResponse

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
