Struct ExtraSponge 

pub struct ExtraSponge<A: SpongeAPI, I: List> { /* private fields */ }

This is a slightly extended generic NewType wrapper around the original SpongeAPI. It is decorated with the IOPattern I intended for this sponge instance.

Implementations

impl<A: SpongeAPI, I: Normalize> ExtraSponge<A, I>

where Norm<I>: ToIOPattern,

pub fn start( domain_separator: Option<u32>, api: A, acc: &mut A::Acc, ) -> ExtraSponge<A, Norm<I>>

Creates a sponge with the IOPatten given as a type parameter. Note that we do not require this pattern to be normalized - instead the constructor will return an ExtraSPonge with a normalized pattern.

impl<A: SpongeAPI, I: Normalize> ExtraSponge<A, I>

pub fn absorb<U>( self, harray: Array<A::Value, U>, acc: &mut A::Acc, ) -> ExtraSponge<A, Use<I, Absorb<U>>>

where U: ArraySize<A::Value>, I: Consume<Absorb<U>>,

This pass-through function is used to absorb elements in the sponge. It calls the underlying API’s absorb function, and then returns a new ExtraSponge but a successful method dispatch to this implementation gaurantees the call is coherent with the IOPattern.

impl<A: SpongeAPI, I: Normalize> ExtraSponge<A, I>

pub fn squeeze<U>( self, harray: &mut Array<A::Value, U>, acc: &mut A::Acc, ) -> ExtraSponge<A, Use<I, Squeeze<U>>>

where U: ArraySize<A::Value>, I: Consume<Squeeze<U>>,

This pass-through function is used to squeeze elements out of the sponge. It calls the underlying API’s squeeze function, and then returns a new ExtraSponge but a successful method dispatch to this implementation gaurantees the call is coherent with the IOPattern.

Trait Implementations

impl<A: Debug + SpongeAPI, I: Debug + List> Debug for ExtraSponge<A, I>

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

Formats the value using the given formatter.

impl<A: SpongeAPI, I: List> Drop for ExtraSponge<A, I>

This implementation of drop is called automatically when the ExtraSponge drops out of scope. It checks that the IOPattern is empty by then, and if it is not, it panics. Otherwise, it calls finalize.

fn drop(&mut self)

Executes the destructor for this type.
