Struct DisableKeysByUsageFeature 

pub struct DisableKeysByUsageFeature { /* private fields */ }

Implements the DisableKeysByUsage / 0x4522 feature.

Implementations

impl DisableKeysByUsageFeature

pub async fn get_capabilities(&self) -> Result<u8, Hidpp20Error>

Retrieves the maximum number of usages that can be disabled at once.

pub async fn disable_keys(&self, usages: &[u8]) -> Result<(), Hidpp20Error>

Disables the given 8-bit keyboard HID usages.

Disabling is cumulative: these usages are added to the disabled set rather than replacing it. A usage of 0 is the list terminator and cannot itself be disabled. More usages than fit in one request are sent over several requests, which the device still accumulates.

pub async fn enable_keys(&self, usages: &[u8]) -> Result<(), Hidpp20Error>

Enables (removes from the disabled set) the given 8-bit keyboard HID usages.

Enabling a usage that is not disabled is a no-op. A usage of 0 terminates the list.

pub async fn enable_all_keys(&self) -> Result<(), Hidpp20Error>

Re-enables every keyboard key.
