}

A LocatedBlock gives information about a block and its location.

Fields

b: ExtendedBlockProto

offset: u64

offset of first byte of block in the file

locs: Vec<DatanodeInfoProto>

Locations ordered by proximity to client ip

corrupt: bool

true if all replicas of a block are corrupt, else false

block_token: TokenProto

is_cached: Vec<bool>

if a location in locs is cached

storage_types: Vec<i32>

storage_i_ds: Vec<String>

block_indices: Option<Vec<u8>>

striped block related fields

used for striped block to indicate block index for each storage

block_tokens: Vec<TokenProto>

each internal block has a block token

Implementations

impl LocatedBlockProto

pub fn storage_types( &self, ) -> FilterMap<Cloned<Iter<'_, i32>>, fn(i32) -> Option<StorageTypeProto>>

Returns an iterator which yields the valid enum values contained in storage_types.

pub fn push_storage_types(&mut self, value: StorageTypeProto)

Appends the provided enum value to storage_types.

pub fn block_indices(&self) -> &[u8]

Returns the value of block_indices, or the default value if block_indices is unset.

Trait Implementations

impl Clone for LocatedBlockProto

fn clone(&self) -> LocatedBlockProto

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LocatedBlockProto

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

Formats the value using the given formatter.

impl Default for LocatedBlockProto

fn default() -> Self

Returns the “default value” for a type.

impl Message for LocatedBlockProto

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for LocatedBlockProto

fn eq(&self, other: &LocatedBlockProto) -> 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.
