Struct BlockMeta 

pub struct BlockMeta {
    pub id: BlockId,
    pub file_offset: u64,
    pub compressed_size: u64,
    pub uncompressed_size: u64,
    pub codec: CodecId,
}

Metadata for a single block in the data region.

Stored in the footer’s block table. Describes where to find the block in the file and how to decompress it.

Fields

id: BlockId

Block identifier.

file_offset: u64

Byte offset of the compressed block within the file.

compressed_size: u64

Size of the block as stored on disk (compressed).

uncompressed_size: u64

Size of the block after decompression.

codec: CodecId

Compression codec used for this block.

Implementations

impl BlockMeta

pub fn file_range(&self) -> Range<u64>

Returns the byte range within the file that contains this block.

Trait Implementations

impl Archive for BlockMeta

where BlockId: Archive, u64: Archive, CodecId: 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 = ArchivedBlockMeta

The archived representation of this type.

type Resolver = BlockMetaResolver

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 Clone for BlockMeta

fn clone(&self) -> BlockMeta

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BlockMeta

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

Formats the value using the given formatter.

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

where BlockId: Archive, <BlockId as Archive>::Archived: Deserialize<BlockId, __D>, u64: Archive, <u64 as Archive>::Archived: Deserialize<u64, __D>, CodecId: Archive, <CodecId as Archive>::Archived: Deserialize<CodecId, __D>,

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

Deserializes using the given deserializer

impl PartialEq for BlockMeta

fn eq(&self, other: &BlockMeta) -> bool

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

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

where BlockId: Serialize<__S>, u64: Serialize<__S>, CodecId: 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.
