Struct TransferRequest 

pub struct TransferRequest<'a> {
    pub bus: u8,
    pub addr: u8,
    /* private fields */
}

A CMD_I2C_TRANSFER request whose structure has been validated.

Fields

bus: u8

addr: u8

The 7-bit address.

Implementations

impl<'a> TransferRequest<'a>

pub fn parse(payload: &'a [u8]) -> Result<Self, I2cError>

Decode and validate a CMD_I2C_TRANSFER payload.

pub const fn from_parts(bus: u8, addr: u8, ops: &'a [u8]) -> Self

Reassemble a request from its parts, for a device that staged the operation list of a request it already validated.

pub const fn encoded_ops(&self) -> &'a [u8]

The operation list in wire form.

pub const fn ops(&self) -> Ops<'a>

The operations, in order.

pub fn shape(&self) -> TransferShape

Sum the list up. Malformed operations are skipped, so call this on a request that Self::parse accepted.

Trait Implementations

impl<'a> Clone for TransferRequest<'a>

fn clone(&self) -> TransferRequest<'a>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for TransferRequest<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a> PartialEq for TransferRequest<'a>

fn eq(&self, other: &TransferRequest<'a>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
