Struct RpcError 

pub struct RpcError {
    pub code: i32,
    pub message: String,
    pub data: Option<Value>,
}

A JSON-RPC 2.0 error object (§5.1), plus a small implementation-defined custom range this protocol occupies for its own conditions.

Fields

code: i32

message: String

data: Option<Value>

Implementations

impl RpcError

pub const PARSE_ERROR: i32 = -32700

pub const INVALID_REQUEST: i32 = -32600

pub const METHOD_NOT_FOUND: i32 = -32601

pub const INVALID_PARAMS: i32 = -32602

pub const INTERNAL_ERROR: i32 = -32603

pub const NOT_SUPPORTED: i32 = -32000

JSON-RPC 2.0 reserves -32000..=-32099 for implementation-defined server errors (§5.1). NOT_SUPPORTED is the first occupant — a capability-gated method (e.g. screenshot) rejects with it on a server whose handshake declared no matching crate::Capability.

pub const UNAUTHORIZED: i32 = -32001

The second occupant of the implementation-defined range: the connection has not presented the server’s per-process token (crate::HandshakeParams), so no method but handshake is dispatched. A client that receives this has the wrong token, or none — it must re-read the discovery line, never retry blindly.

pub fn new(code: i32, message: impl Into<String>) -> Self

pub fn not_supported(message: impl Into<String>) -> Self

pub fn unauthorized(message: impl Into<String>) -> Self
