Trait Implementations

impl<E, First: Debug + Decoder, Second: Debug + Decoder, Fun: Debug + FnOnce(First::Value) -> Result<Second, E>> Debug for ThenTry<E, First, Second, Fun>

where E: From<First::Error> + From<Second::Error> + Debug,

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

Formats the value using the given formatter.

impl<E, First: Decoder, Second: Decoder, Fun: FnOnce(First::Value) -> Result<Second, E>> Decoder for ThenTry<E, First, Second, Fun>

where E: From<First::Error> + From<Second::Error>,

type Value = <Second as Decoder>::Value

The type of value produced by this decoder.

type Error = E

Decoding error.

fn decode_chunk(&mut self, bytes: &mut &[u8]) -> Result<(), Self::Error>

Processes nex chunk of bytes and updates the cursor.

fn end(self) -> Result<Self::Value, Self::Error>

Called when decoding has ended or there are no more bytes.

fn bytes_received(&mut self, bytes: &[u8]) -> Result<usize, Self::Error>

Processes nex chunk of bytes without updating the cursor.

fn then<R: Decoder, F: FnOnce(Self::Value) -> R>( self, fun: F, ) -> Then<Self, R, F>

Chains another decoder after this one finishes such that the value of this one is used to initialize the next one.

fn then_try<E, R: Decoder, F: FnOnce(Self::Value) -> Result<R, E>>( self, fun: F, ) -> ThenTry<E, Self, R, F>

where E: From<Self::Error> + From<R::Error>,

Chains another decoder after this one finishes such that the value of this one is used to initialize the next one.

fn chain<D: Decoder>(self, following: D) -> Chain<Self, D>

Chains another decoder after this one to decode two values.

fn wrap_sub_decode<F: FnOnce() -> ControlFlow<Result<(), Self::Error>, Infallible>>( f: F, ) -> Result<(), Self::Error>

Helper for using sub_decode.
