Struct BlockChecksumOptionsProto

pub struct BlockChecksumOptionsProto {
    pub block_checksum_type: Option<i32>,
    pub stripe_length: Option<u64>,
}

Algorithms/types denoting how block-level checksums are computed using lower-level chunk checksums/CRCs. These options should be kept in sync with org.apache.hadoop.hdfs.protocol.BlockChecksumOptions.

Fields

block_checksum_type: Option<i32>

stripe_length: Option<u64>

Only used if blockChecksumType specifies a striped format, such as COMPOSITE_CRC. If so, then the blockChecksum in the response is expected to be the concatenation of N crcs, where N == ((requestedLength - 1) / stripedLength) + 1

Implementations

impl BlockChecksumOptionsProto

pub fn block_checksum_type(&self) -> BlockChecksumTypeProto

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

pub fn set_block_checksum_type(&mut self, value: BlockChecksumTypeProto)

Sets block_checksum_type to the provided enum value.

pub fn stripe_length(&self) -> u64

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

Trait Implementations

impl Clone for BlockChecksumOptionsProto

fn clone(&self) -> BlockChecksumOptionsProto

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BlockChecksumOptionsProto

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

Formats the value using the given formatter.

impl Default for BlockChecksumOptionsProto

fn default() -> Self

Returns the “default value” for a type.

impl Message for BlockChecksumOptionsProto

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 BlockChecksumOptionsProto

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