Enum ProtocolError 

#[non_exhaustive]
pub enum ProtocolError {
    MissingContentLength,
    InvalidContentLength(String),
    RequestCancelled,
    CliStartupTimeout,
    CliStartupFailed,
    VersionMismatch {
        server: u32,
        min: u32,
        max: u32,
    },
    VersionChanged {
        previous: u32,
        current: u32,
    },
}

Specific protocol-level errors in the JSON-RPC transport or CLI lifecycle.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

MissingContentLength

Missing Content-Length header in a JSON-RPC message.

InvalidContentLength(String)

Invalid Content-Length header value.

RequestCancelled

A pending JSON-RPC request was cancelled (e.g. the response channel was dropped).

CliStartupTimeout

The CLI process did not report a listening port within the timeout.

CliStartupFailed

The CLI process exited before reporting a listening port.

VersionMismatch

The CLI server’s protocol version is outside the SDK’s supported range.

Fields

server: u32

Version reported by the server.

min: u32

Minimum version supported by this SDK.

max: u32

Maximum version supported by this SDK.

VersionChanged

The CLI server’s protocol version changed between calls.

Fields

previous: u32

Previously negotiated version.

current: u32

Newly reported version.

Trait Implementations

impl Debug for ProtocolError

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

Formats the value using the given formatter.

impl Display for ProtocolError

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

Formats the value using the given formatter.

impl Error for ProtocolError

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.
