Trait FromCharacteristic

pub trait FromCharacteristic: Sized {
    const UUID: Uuid;

    // Required methods
    fn from_chr(
        characteristic: Characteristic,
        value: &[u8],
    ) -> Result<Self, Error>;
    fn update(&mut self, new_value: &[u8]) -> Result<&mut Self, Error>;

    // Provided method
    fn try_read<T: GattTypes>(
        characteristic: Characteristic,
        service: &T::PeerService,
    ) -> impl Future<Output = Result<Self, Error>> { ... }
}

Implement when a type can be deserialized from a characteristic value.

Required Associated Constants

const UUID: Uuid

Required Methods

fn from_chr(characteristic: Characteristic, value: &[u8]) -> Result<Self, Error>

Create this type from a Characteristic and an initial value.

fn update(&mut self, new_value: &[u8]) -> Result<&mut Self, Error>

Attempt to update the type when supplied with the new_value, which may or may not be the complete value.

Provided Methods

fn try_read<T: GattTypes>( characteristic: Characteristic, service: &T::PeerService, ) -> impl Future<Output = Result<Self, Error>>

Attempt to read a characteristic if it matches the provided characteristic UUID.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
