Struct RpcError 

pub struct RpcError {
    pub op_index: usize,
    pub status: u32,
    pub message: String,
    pub transport_kind: Option<TransportKind>,
}

An error from the low-level client: either an NFS4ERR_* status reported by the server for a compound operation, or a transport/RPC-level failure.

Callers can inspect status directly instead of parsing error strings.

op_index is the index of the failing operation in the caller’s request slice: the batched compound helpers (vread_native, vwrite_native, getattr_many, …) translate compound positions to caller-relative indices before returning. For single-operation helpers it is the position within the compound (typically 2: SEQUENCE, PUTFH, op). Transport failures always report op_index == 0.

Fields

op_index: usize

Index of the failing operation within the compound.

status: u32

The failing op’s NFS4ERR_* status, or STATUS_TRANSPORT.

message: String

Human-readable context.

transport_kind: Option<TransportKind>

Present only for transport/RPC failures.

Implementations

impl RpcError

pub fn op(op_index: usize, status: u32) -> RpcError

An NFS status from a specific compound operation.

pub fn transport(message: impl Into<String>) -> RpcError

A transport / RPC-level failure (no NFS status available).

pub fn transport_with_kind( kind: TransportKind, message: impl Into<String>, ) -> RpcError

pub fn from_io(error: Error) -> RpcError

Preserve classification at an I/O boundary without inspecting its text.

pub fn is_transport(&self) -> bool

Whether this is a transport failure rather than an NFS status.

pub fn with_op_index(self, index: usize) -> RpcError

Re-attribute this error to a different operation index (used by the batched helpers to translate compound positions to caller indices).

Trait Implementations

impl Clone for RpcError

fn clone(&self) -> RpcError

impl Eq for RpcError

impl Error for RpcError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for RpcError

fn eq(&self, other: &RpcError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
