Fields

peripheral_free: extern "C" fn(_: *mut Peripheral)

Frees the memory associated with a peripheral.

error_message: extern "C" fn(_: c_int) -> *const c_uchar

Returns an error message associated with a Plugin error code.

attribute_name: extern "C" fn(peripheral: *const Peripheral, id: size_t, buffer: *mut c_uchar, length: size_t) -> c_int

Writes the name of an attribute to a buffer that is provided by the caller.

attribute_value: extern "C" fn(peripheral: *const Peripheral, id: size_t, value: *mut Value) -> c_int

Writes the value of an attribute to a Value instance that is provided by the caller.

set_attribute_value: extern "C" fn(peripheral: *mut Peripheral, id: size_t, value: *const Value) -> c_int

Sets the value of an attribute.
