Expand description

Driver-owned chain returned by used-ring consumption.

Implementations§

Source§

impl<C> UsedChain<C>

Source

pub const fn new(id: ChainId, used: UsedLength, chain: C) -> Self

Construct a used-chain result.

Source

pub const fn id(&self) -> ChainId

Returned chain identity.

Source

pub const fn used(&self) -> UsedLength

Exact number of bytes written by the device.

Source

pub const fn chain(&self) -> &C

Borrow the returned driver chain.

Source

pub fn into_parts(self) -> (ChainId, UsedLength, C)

Recover the identity, used length, and driver chain.

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