Enum ComposeOverviewError 

pub enum ComposeOverviewError {
    InvalidIncludeKeySchemaTypes,
    UnknownMem {
        name: String,
        writable_mems: Vec<String>,
    },
}

Typed input failures the composer surfaces. The MCP wrapper maps each variant to its existing envelope (INVALID_INPUT, UNKNOWN_MEM); the full CLI does the same to its CLI error codes.

Variants

InvalidIncludeKeySchemaTypes

The include set carries schema_types, a removed key. The recovery is to call the per-schema reader instead — wording hint stays surface-specific (see memstead_schema(name=...) / memstead type ...).

UnknownMem

args.mem names a mem that isn’t visible in this workspace. The composer surfaces the visible roster (writable + read-only mounts) so the caller can correct the input — scoping a read overview to a registry-installed read-only mem is legitimate, so the accepted set is the visible roster, not the writable subset. The field name stays writable_mems for wire-shape stability; it now carries the visible roster.

Fields

name: String

writable_mems: Vec<String>

Trait Implementations

impl Debug for ComposeOverviewError

impl Error for ComposeOverviewError

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.
