Enum LogDatum

    EnumValue(u64),
    UnsignedValue(u64),

}

What a Trend Log record carries: a sampled value, the error that stopped the sample, a status change of the log, or a clock change.

On the wire each alternative takes a context tag, 0 to 10 in declaration order; the encoding crate owns that numbering.

Variants

LogStatus(LogStatus)

A status change of the log itself.

BooleanValue(bool)

A BOOLEAN value.

RealValue(f32)

A REAL value.

EnumValue(u64)

An ENUMERATED value. A logging device may hold these to 32 bits but need not, so a decoded record keeps up to 64.

UnsignedValue(u64)

An Unsigned value, up to 64 bits.

SignedValue(i64)

An INTEGER value, up to 64 bits.

BitstringValue

A BIT STRING value.

Fields

unused_bits: u8

Padding bits at the end of the final octet, 0 to 7.

data: Vec<u8>

The bit data.

NullValue

A NULL value.

Failure

The error that kept the value from being logged.

Fields

error_class: u32

Raw BACnet error class value.

error_code: u32

Raw BACnet error code value.

TimeChange(f32)

The device clock moved by this many seconds; zero when unknown.

AnyValue(Vec<u8>)

A value of any other datatype, as the tagged encoding a property read carries for it: one or more complete values, context tags balanced.
