Struct i2c::ReadFlags

pub struct ReadFlags { /* fields omitted */ }

Flags to work around device quirks.

Methods

impl ReadFlags

pub const RECEIVE_LEN: ReadFlags

RECEIVE_LEN: ReadFlags = ReadFlags{bits: 1,}

The first received byte will indicate the remaining length of the transfer.

pub const NACK: ReadFlags

NACK: ReadFlags = ReadFlags{bits: 2,}

NACK bit is generated for this read.

pub const REVERSE_RW: ReadFlags

REVERSE_RW: ReadFlags = ReadFlags{bits: 4,}

Flips the meaning of the read/write address bit for misbehaving devices.

pub const NO_START: ReadFlags

NO_START: ReadFlags = ReadFlags{bits: 8,}

Do not generate a START condition or the address start byte. When used for the first message, a START condition is still generated.

This can be used to combine multiple buffers into a single I2C transfer, usually without a direction change.

pub const STOP: ReadFlags

STOP: ReadFlags = ReadFlags{bits: 16,}

Force a STOP condition after this message.

pub fn empty() -> ReadFlags

Returns an empty set of flags.

pub fn all() -> ReadFlags

Returns the set containing all flags.

pub fn bits(&self) -> u16

Returns the raw value of the flags currently stored.

pub fn from_bits(bits: u16) -> Option<ReadFlags>

Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.

pub fn from_bits_truncate(bits: u16) -> ReadFlags

Convert from underlying bit representation, dropping any bits that do not correspond to flags.

pub fn is_empty(&self) -> bool

Returns true if no flags are currently stored.

pub fn is_all(&self) -> bool

Returns true if all flags are currently set.

pub fn intersects(&self, other: ReadFlags) -> bool

Returns true if there are flags common to both self and other.

pub fn contains(&self, other: ReadFlags) -> bool

Returns true all of the flags in other are contained within self.

pub fn insert(&mut self, other: ReadFlags)

Inserts the specified flags in-place.

pub fn remove(&mut self, other: ReadFlags)

Removes the specified flags in-place.

pub fn toggle(&mut self, other: ReadFlags)

Toggles the specified flags in-place.

pub fn set(&mut self, other: ReadFlags, value: bool)

Inserts or removes the specified flags depending on the passed value.
