[−][src]Trait i2cdev::core::I2CTransfer

pub trait I2CTransfer<'a> {
    type Error: Error;
    type Message: I2CMessage<'a>;
    fn transfer(
        &mut self, 
        msgs: &'a mut [Self::Message]
    ) -> Result<u32, Self::Error>;
}

Interface to an I2C Bus from an I2C Master

This is used when the client wants to interact directly with the bus without specifying an I2C slave address up-front, either because it needs to communicate with multiple addresses without creatings separate I2CDevice objects, or because it wants to make used of the I2C_RDWR ioctl which allows the client to send and transmit multiple sets I2C data in a single operation, potentially to different I2C slave addresses.

Typical implementations will store state with references to the bus in use. The trait is based on the Linux i2cdev interface.
