Errors produced while acquiring, verifying, or running the embedded server.

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.

UnsupportedPlatform

No .mcpb bundle is published for the host OS/arch.

Fields

os: &'static str

arch: &'static str

NoHomeDir

The home directory could not be resolved (HOME / USERPROFILE unset).

Http

Downloading the bundle failed.

Fields

url: String

message: String

ChecksumMismatch

The downloaded bundle did not match the sha256 pin baked into the crate.

Fields

bundle: String

expected: String

actual: String

Bundle(String)

The .mcpb bundle is malformed (bad zip, missing or invalid manifest).

Io(Error)

Filesystem error.

Spawn(Error)

The server process could not be spawned.

Mcp(String)

MCP handshake or client error.

OverrideNotFound

A path given via an env override or builder option does not exist.

Fields

what: &'static str

path: PathBuf

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 From<Error> for Error

fn from(e: Error) -> Self

Converts to this type from the input type.
