Trait Implementations

impl<'d, M: Mode> ErrorType for Spi<'d, M>

type Error = Error

Error type.

impl<'d, M: Mode> SetConfig for Spi<'d, M>

type Config = Config

The configuration type used by this driver.

type ConfigError = ConfigError

The error type that can occur if set_config fails.

fn set_config(&mut self, config: &Self::Config) -> Result<(), ConfigError>
