Enum LogValue 

pub enum LogValue {
    BooleanValue(bool),
    RealValue(f32),
    EnumValue(u64),
    UnsignedValue(u64),
    SignedValue(i64),
    BitstringValue {
        unused_bits: u8,
        data: Vec<u8>,
    },
    NullValue,
    Failure {
        error_class: u32,
        error_code: u32,
    },
    AnyValue(Vec<u8>),
}

One sampled value, or the error that stopped the sample, in a Trend Log Multiple record (Clause 12.30.19).

These are the per-member alternatives of Clause 21’s BACnetLogData. On the wire they take context tags 0 to 8 in declaration order; the encoding crate owns that numbering, which differs from LogDatum’s.

Variants

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 this member from being logged.

Fields

error_class: u32

Raw BACnet error class value.

error_code: u32

Raw BACnet error code value.

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.
