Struct Pdu 

pub struct Pdu {
    pub pdu_type: PduType,
    pub request_id: i32,
    pub error_status: i32,
    pub error_index: i32,
    pub varbinds: Vec<VarBind>,
}

Generic PDU structure for request/response operations.

Fields

pdu_type: PduType

PDU type

request_id: i32

Request ID for correlating requests and responses

error_status: i32

Error status (0 for requests, error code for responses)

error_index: i32

Error index (1-based index of problematic varbind)

varbinds: Vec<VarBind>

Variable bindings

Implementations

impl Pdu

pub fn get_request(request_id: i32, oids: &[Oid]) -> Self

Create a new GET request PDU.

pub fn get_next_request(request_id: i32, oids: &[Oid]) -> Self

Create a new GETNEXT request PDU.

pub fn set_request(request_id: i32, varbinds: Vec<VarBind>) -> Self

Create a new SET request PDU.

pub fn get_bulk( request_id: i32, non_repeaters: i32, max_repetitions: i32, varbinds: Vec<VarBind>, ) -> Self

Create a GETBULK request PDU.

Note: For GETBULK, error_status holds non_repeaters and error_index holds max_repetitions.

pub fn encode(&self, buf: &mut EncodeBuf)

Encode to BER.

pub fn decode(decoder: &mut Decoder) -> Result<Self>

Decode from BER (after tag has been peeked).

pub fn is_error(&self) -> bool

Check if this is an error response.

pub fn error_status_enum(&self) -> ErrorStatus

Get the error status as an enum.

pub fn to_response(&self) -> Self

Create a Response PDU from this PDU (for Inform handling).

The response copies the request_id and variable bindings, sets error_status and error_index to 0, and changes the PDU type to Response.

pub fn to_error_response( &self, error_status: ErrorStatus, error_index: i32, ) -> Self

Create a Response PDU with specific error status.

pub fn is_notification(&self) -> bool

Check if this is a notification PDU (Trap or Inform).

pub fn is_confirmed(&self) -> bool

Check if this is a confirmed-class PDU (requires response).

Trait Implementations

impl Clone for Pdu

fn clone(&self) -> Pdu

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Pdu

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

Formats the value using the given formatter.
