A configuration value that violates a protocol or local safety bound.

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.

ZeroBaudRate

A baud rate of zero cannot be used to derive bit-time limits.

TimingOverflow

A derived timing calculation overflowed its arithmetic.

MaxMasterOutOfRange

Max_Master is a seven-bit station address.

Fields

value: u8

Supplied Max_Master value.

StationExceedsMaxMaster

This station cannot be beyond Max_Master.

Fields

station: u8

Local station address.

max_master: u8

Configured Max_Master value.

MaxInfoFramesOutOfRange

Max_Info_Frames must be in the inclusive 1..=255 range.

Fields

value: u8

Supplied Max_Info_Frames value.

FrameAbortOutOfRange

T_frame_abort is outside the 60-bit-time through 100 ms range.

Fields

value: Duration

Supplied frame-abort duration.

minimum: Duration

Minimum permitted duration.

maximum: Duration

Maximum permitted duration.

FrameGapTooLong

T_frame_gap is longer than 20 bit times.

Fields

value: Duration

Supplied frame-gap duration.

maximum: Duration

Maximum permitted duration.

PostdriveTooLong

T_postdrive is longer than 15 bit times.

Fields

value: Duration

Supplied postdrive duration.

maximum: Duration

Maximum permitted duration.

ReplyDelayTooLong

T_reply_delay cannot exceed 250 ms.

Fields

value: Duration

Supplied reply-delay duration.

maximum: Duration

Maximum permitted duration.

ReplyMarginTooLong

The reply transmit margin must leave part of T_reply_delay for the application to answer.

Fields

margin: Duration

Supplied margin.

reply_delay: Duration

Configured T_reply_delay.

ReplyTimeoutOutOfRange

T_reply_timeout must be between 255 and 300 ms.

Fields

value: Duration

Supplied reply-timeout duration.

minimum: Duration

Minimum permitted duration.

maximum: Duration

Maximum permitted duration.

TurnaroundTooShort

T_turnaround must cover at least 40 bit times.

Fields

value: Duration

Supplied turnaround duration.

minimum: Duration

Minimum permitted duration.

TurnaroundExceedsUsageDelay

T_turnaround cannot exceed the maximum T_usage_delay response window.

Fields

turnaround: Duration

Supplied turnaround duration.

usage_delay: Duration

Configured usage-delay duration.

UsageDelayTooLong

T_usage_delay cannot exceed 15 ms.

Fields

value: Duration

Supplied usage-delay duration.

maximum: Duration

Maximum permitted duration.

UsageTimeoutOutOfRange

T_usage_timeout must be between 20 and 35 ms.

Fields

value: Duration

Supplied usage-timeout duration.

minimum: Duration

Minimum permitted duration.

maximum: Duration

Maximum permitted duration.

ZeroLocalDuration

A local queue age or watchdog of zero would disable the safety bound.

Fields

field: LocalDurationField

Local duration setting that was zero.

ZeroLocalLimit

A local scheduling ratio or starvation limit of zero is invalid.

Fields

field: LocalLimitField

Local count or ratio setting that was zero.

MultipleFrameRatioOutOfRange

Multiple-frame ratio is a percentage and cannot exceed 100.

Fields

value: u8

Supplied percentage value.

TransmitWatchdogTooShort

The transmit watchdog would abort the longest frame this configuration sends before the driver could go off: a standard frame of 511 octets takes 1.06 s at 4800 baud, and an extended one of 1516 octets 1.58 s at 9600. See MstpCoreConfig::minimum_transmit_watchdog; the baud-rate constructors and MstpCoreConfig::with_extended_frames set one that clears it.

Fields

value: Duration

Supplied watchdog.

minimum: Duration

The shortest watchdog accepted, MstpCoreConfig::minimum_transmit_watchdog.

ExtendedStorageTooSmall

MstpCoreConfig::extended_frames is on, but a buffer the core was given can’t hold the largest extended frame or NPDU. Only MasterCore::new and MasterCore::from_parts report it, since only they see the buffers.

Fields

buffer: CoreBuffer

The buffer that is too small.

length: usize

Its size in octets.

minimum: usize

The size extended frames need: the longest extended frame on the wire for the receive storage and the transmit frame, the longest NPDU one carries for a delivery slot and a queue slot.

ReceiveStorageTooSmall

The receive storage the core was given can’t hold even the shortest frame. Only MasterCore::new and MasterCore::from_parts report it.

Fields

length: usize

Supplied storage length.

minimum: usize

MIN_RX_STORAGE.
