Trait FixedGattValue

pub trait FixedGattValue: FromGatt {
    const SIZE: usize;

    // Required methods
    fn from_gatt(data: &[u8]) -> Result<Self, FromGattError>;
    fn as_gatt(&self) -> &[u8];
}

Trait to allow conversion of a fixed size type to and from a byte slice

Required Associated Constants

const SIZE: usize

Size of the type in bytes

Required Methods

fn from_gatt(data: &[u8]) -> Result<Self, FromGattError>

Converts from gatt bytes. Must return FromGattError::InvalidLength if data.len != Self::SIZE

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

Converts to gatt bytes. Must return a slice of len Self::SIZE

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.
