Enum ErrorCode 

#[repr(u8)]
pub enum ErrorCode {
    InvalidArgument = 1,
    Unauthenticated = 2,
    PermissionDenied = 3,
    NotFound = 4,
    FailedPrecondition = 5,
    Unavailable = 6,
    DeadlineExceeded = 7,
    ResourceExhausted = 8,
    Cancelled = 9,
    ProtocolError = 10,
    Internal = 11,
    AlreadyExists = 12,
}

Stable wire error codes whose discriminants are part of protocol version 3.

Variants

InvalidArgument = 1

A request field is malformed or violates the contract.

Unauthenticated = 2

The operation credential is missing, expired, or unverifiable.

PermissionDenied = 3

The verified credential does not authorize the operation.

NotFound = 4

No Binding or Pipe matches the requested Destination or identifier.

FailedPrecondition = 5

The current state does not allow the operation.

Unavailable = 6

The serving side cannot accept the operation at this time.

DeadlineExceeded = 7

The operation did not reach a terminal result within its deadline.

ResourceExhausted = 8

Covers admission, capacity, queue, and size limits.

Cancelled = 9

The initiator abandoned the operation before it completed.

ProtocolError = 10

A peer violated the wire protocol or state-machine contract.

Internal = 11

A local invariant or task failed without a peer protocol violation.

AlreadyExists = 12

The requested registration already exists.

Implementations

impl ErrorCode

pub const fn metric_name(self) -> &'static str

Canonical snake_case name for metric labels and structured logs.

pub fn from_wire(value: u8) -> Option<Self>

Decodes the wire byte; None for values outside the contract.
