Enum CollectionItem

pub enum CollectionItem {
    Physical,
    Application,
    Logical,
    Report,
    NamedArray,
    UsageSwitch,
    UsageModifier,
    Reserved {
        value: u8,
    },
    VendorDefined {
        value: u8,
    },
}

See Section 6.2.2.6. A collection groups several items together.

A Collection item identifies a relationship between two or more data (Input, Output, or Feature.) For example, a mouse could be described as a collection of two to four data (x, y, button 1, button 2). While the Collection item opens a collection of data, the MainItem::EndCollection item closes a collection.

Trait Implementations

impl Clone for CollectionItem

fn clone(&self) -> CollectionItem

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CollectionItem

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<&CollectionItem> for u8

fn from(c: &CollectionItem) -> u8

Converts to this type from the input type.

impl From<CollectionItem> for ItemType

fn from(item: CollectionItem) -> ItemType

Converts to this type from the input type.

impl From<u8> for CollectionItem

fn from(v: u8) -> CollectionItem

Converts to this type from the input type.

impl PartialEq for CollectionItem

fn eq(&self, other: &CollectionItem) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<&[u8]> for CollectionItem

type Error = HidError

The type returned in the event of a conversion error.

fn try_from(bytes: &[u8]) -> Result<CollectionItem, HidError>

Performs the conversion.

impl Copy for CollectionItem

impl StructuralPartialEq for CollectionItem
