Struct ShaSetContext 

pub struct ShaSetContext {
    pub context_id: Option<usize>,
    pub algo: ShaAlgo,
    pub hash_state: [u8; 64],
}

Allocate a server-side SHA context slot (or overwrite an existing one) and seed it with the supplied hash state. context_id = None on first use; the server allocates a slot and returns its id. Subsequent calls with the returned id overwrite the state.

Fields

context_id: Option<usize>

None → allocate a new slot; Some(id) → overwrite existing slot.

algo: ShaAlgo

hash_state: [u8; 64]

Intermediate hash state in standard digest byte order (BE per word). SHA-224/256 use the first 32 bytes; SHA-384/512 use all 64.

Trait Implementations

impl Archive for ShaSetContext

where Option<usize>: Archive, ShaAlgo: Archive, [u8; 64]: Archive,

const COPY_OPTIMIZATION: CopyOptimization<Self>

An optimization flag that allows the bytes of this type to be copied directly to a writer instead of calling serialize.

type Archived = ArchivedShaSetContext

The archived representation of this type.

type Resolver = ShaSetContextResolver

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.

fn resolve(&self, resolver: Self::Resolver, out: Place<Self::Archived>)

Creates the archived version of this value at the given position and writes it to the given output.

impl BlockingArchive for ShaSetContext

type Response = Result<usize, CryptoError>

response type for this message

impl Debug for ShaSetContext

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

Formats the value using the given formatter.

impl<__D: Fallible + ?Sized> Deserialize<ShaSetContext, __D> for Archived<ShaSetContext>

where Option<usize>: Archive, <Option<usize> as Archive>::Archived: Deserialize<Option<usize>, __D>, ShaAlgo: Archive, <ShaAlgo as Archive>::Archived: Deserialize<ShaAlgo, __D>, [u8; 64]: Archive, <[u8; 64] as Archive>::Archived: Deserialize<[u8; 64], __D>,

fn deserialize( &self, deserializer: &mut __D, ) -> Result<ShaSetContext, <__D as Fallible>::Error>

Deserializes using the given deserializer

impl MessageId for ShaSetContext

const ID: MessageId = 9usize

unique message identifier

const SERVER: &'static str = "os/crypto"

target server name

impl<__S: Fallible + ?Sized> Serialize<__S> for ShaSetContext

where Option<usize>: Serialize<__S>, ShaAlgo: Serialize<__S>, [u8; 64]: Serialize<__S>,

fn serialize( &self, serializer: &mut __S, ) -> Result<<Self as Archive>::Resolver, <__S as Fallible>::Error>

Writes the dependencies for the object and returns a resolver that can create the archived type.
