Struct wasmer_journal::concrete::archived::JournalEntryHeader

pub(crate) struct JournalEntryHeader {
    pub record_type: u16,
    pub record_size: u64,
}

The journal log entries are serializable which allows them to be written directly to a file

Note: This structure is versioned which allows for changes to the journal entry types without having to worry about backward and forward compatibility

Fields

record_type: u16

record_size: u64

Trait Implementations

impl Archive for JournalEntryHeader

where u16: Archive, u64: Archive,

type Archived = ArchivedJournalEntryHeader

The archived representation of this type.

type Resolver = JournalEntryHeaderResolver

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

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.

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 Clone for JournalEntryHeader

fn clone(&self) -> JournalEntryHeader

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for JournalEntryHeader

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

Formats the value using the given formatter.

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

where u16: Archive, <u16 as Archive>::Archived: Deserialize<u16, __D>, u64: Archive, <u64 as Archive>::Archived: Deserialize<u64, __D>,

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

Deserializes using the given deserializer

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

where u16: Serialize<__S>, u64: 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.
