Struct ReportSize 

pub struct ReportSize(/* private fields */);

Unsigned integer specifying the size of the report fields in bits.

This allows the parser to build an item map for the report handler to use.

Implementations

impl ReportSize

pub const PREFIX: u8 = 116u8

Prefix consists of tag(bit 7-4), type(bit 3-2) and size(bit 1-0). The “size” part is set to 00 in this constant value.

pub fn new(raw: &[u8]) -> Result<Self, HidError>

Create an item with prefix check.

pub unsafe fn new_unchecked(raw: &[u8]) -> Self

Create an item WITHOUT prefix check.

Safety

Must ensure that the prefix part is correct.

pub fn prefix(&self) -> u8

Get prefix part of the item. Equivalent to item.as_ref()[0].

pub fn data(&self) -> &[u8]

Get data part of the item. Equivalent to &item.as_ref()[1..].

pub fn new_with(data: &[u8]) -> Result<Self, HidError>

Create an item with specific data.

NOTE: data size must be: 0, 1, 2 or 4.

pub fn set_data(&mut self, data: &[u8]) -> Result<&mut Self, HidError>

Set data part of the item.

NOTE: data size must be: 0, 1, 2 or 4.

pub fn data_mut(&mut self) -> &mut [u8]

Get mutable data part of the item.

Trait Implementations

impl AsRef<[u8]> for ReportSize

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for ReportSize

fn clone(&self) -> ReportSize

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ReportSize

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

Formats the value using the given formatter.

impl Default for ReportSize

fn default() -> Self

Returns the “default value” for a type.

impl Display for ReportSize

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

Formats the value using the given formatter.

impl PartialEq for ReportSize

fn eq(&self, other: &ReportSize) -> 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.
