Why the spool ledger refused a command, each cause carrying what a client needs to choose the next valid request.

Variants

UnknownSpool

No spool was ever registered under this identifier.

Fields

spool_id: SpoolId

The identifier the command named.

RetiredSpool

The spool is retired, and takes no further command.

Fields

spool_id: SpoolId

The retired spool.

NothingToConfirm

The spool named is already on the tool, and nothing is pending there or marked on it for a load to confirm.

Fields

tool: i64

The tool the spool is already on.

InvalidAdjustmentFigure

A figure the command gave is not one the field can hold: not a number, or out of the field’s range.

Fields

field: SpoolField

The field the figure was given for.

value: f64

The figure given; always a number, because a figure JSON cannot carry is refused as it would be written rather than written as null.

TareRequired

A scale reading was given for a spool with no tare, so it cannot be turned into a figure.

Fields

spool_id: SpoolId

The spool with no tare.

DensityRequired

The material has no known density, so the command needs one.

Fields

material: String

The material, as given and trimmed.

spool_id: Option<SpoolId>

The spool, when the command was about one that exists; absent for a registration.

MissingField

A field the command needs was empty or absent.

Fields

field: SpoolField

The field; for a correction naming neither figure, remaining_g, which gross_g may stand in for.

ConflictingFields

The command gave fields only one of which it may carry.

Fields

fields: Vec<SpoolField>

Every field given that conflicts, in the command’s own order.

UnknownTool

The command named a tool the printer cannot have.

Fields

tool: i64

The tool named.

NotLoaded

The spool is loaded on no tool, so there is nothing to unload.

Fields

spool_id: SpoolId

The spool.

LedgerRefused

The ledger refused the write the command made, because the spools changed under it; reading them again shows how.
