Enum ComposeHealthError 

pub enum ComposeHealthError {
    UnknownMem {
        name: String,
        writable_mems: Vec<String>,
    },
    MemQuarantined(String),
    InvalidTargetSchema {
        raw: String,
        reason: String,
    },
    Engine(EngineError),
}

Typed input failures the composer surfaces. The MCP wrapper maps each variant to its existing envelope (UNKNOWN_MEM, INVALID_INPUT) and the engine fault to its typed translator, so the wire code stays put.

Variants

UnknownMem

args.mem names a mem that isn’t writable in this workspace. The composer surfaces the sorted writable roster so the wrapper can echo it in the UNKNOWN_MEM envelope.

Fields

name: String

writable_mems: Vec<String>

MemQuarantined(String)

args.mem names a QUARANTINED mem — the scope refuses with the typed quarantine reason rather than reporting the mem unknown (agent-trust plan 04). The wrapper maps it through its ordinary engine-error path via Engine::unknown_mem_error.

InvalidTargetSchema

args.target_schema did not parse as a name@x.y.z ref. reason is the parser’s message, surfaced verbatim in the INVALID_INPUT envelope’s details.reason.

Fields

raw: String

reason: String

Engine(EngineError)

A backend fault from the conformance / consistency scan. The wrapper routes it through the typed EngineError translator unchanged.

Trait Implementations

impl Debug for ComposeHealthError

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

Formats the value using the given formatter.

impl Display for ComposeHealthError

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

Formats the value using the given formatter.

impl Error for ComposeHealthError

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<EngineError> for ComposeHealthError

fn from(source: EngineError) -> Self

Converts to this type from the input type.
