pub enum Detail {
    Bool {
        bit: u8,
    },

Expand description

The different kind of settings along with descriptor bits that depend on the kind.

Variants§

§

Bool

A boolean setting only uses one bit, numbered from LSB.

Fields

§bit: u8

0-7.

§

Num

A numerical setting uses the whole byte.

§

Enum

An Enum setting uses a range of enumerators.

Fields

§last: u8

Numerical value of last enumerator, allowing for 1-256 enumerators.

§enumerators: u16

First enumerator in the ENUMERATORS table.

§

Preset

A preset is not an individual setting, it is a collection of settings applied at once.

The Descriptor::offset field refers to the PRESETS table.

Implementations§

source§

impl Detail

source

pub fn is_preset(self) -> bool

Check if a detail is a Detail::Preset. Useful because the Descriptor offset field has a different meaning when the detail is a preset.
