Fields

header: ClientOperationHeaderProto

targets: Vec<DatanodeInfoProto>

source: Option<DatanodeInfoProto>

stage: i32

pipeline_size: u32

min_bytes_rcvd: u64

max_bytes_rcvd: u64

latest_generation_stamp: u64

requested_checksum: ChecksumProto

The requested checksum mechanism for this block write.

caching_strategy: Option<CachingStrategyProto>

storage_type: Option<i32>

target_storage_types: Vec<i32>

allow_lazy_persist: Option<bool>

Hint to the DataNode that the block can be allocated on transient storage i.e. memory and written to disk lazily. The DataNode is free to ignore this hint.

pinning: Option<bool>

whether to pin the block, so Balancer won’t move it.

target_pinnings: Vec<bool>

storage_id: Option<String>

target_storage_ids: Vec<String>

Implementations

impl OpWriteBlockProto

pub fn stage(&self) -> BlockConstructionStage

Returns the enum value of stage, or the default if the field is set to an invalid enum value.

pub fn set_stage(&mut self, value: BlockConstructionStage)

Sets stage to the provided enum value.

pub fn storage_type(&self) -> StorageTypeProto

Returns the enum value of storage_type, or the default if the field is unset or set to an invalid enum value.

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

Sets storage_type to the provided enum value.

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

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

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

Appends the provided enum value to target_storage_types.

pub fn allow_lazy_persist(&self) -> bool

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

pub fn pinning(&self) -> bool

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

pub fn storage_id(&self) -> &str

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

Trait Implementations

impl Clone for OpWriteBlockProto

fn clone(&self) -> OpWriteBlockProto

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OpWriteBlockProto

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

Formats the value using the given formatter.

impl Default for OpWriteBlockProto

fn default() -> Self

Returns the “default value” for a type.

impl Message for OpWriteBlockProto

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,

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 OpWriteBlockProto

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