Struct BodyCompression

pub struct BodyCompression<'a> {
    pub _tab: Table<'a>,
}

Optional compression for the memory buffers constituting IPC message bodies. Intended for use with RecordBatch but could be used for other message types

Fields

_tab: Table<'a>

Implementations

impl<'a> BodyCompression<'a>

pub const VT_CODEC: u16 = 4u16

pub const VT_METHOD: u16 = 6u16

pub unsafe fn init_from_table(table: Table<'a>) -> BodyCompression<'a>

pub fn create<'bldr, 'args, 'mut_bldr>( _fbb: &'mut_bldr mut FlatBufferBuilder<'bldr>, args: &'args BodyCompressionArgs, ) -> WIPOffset<BodyCompression<'bldr>>

where 'bldr: 'args, 'args: 'mut_bldr,

pub fn codec(&self) -> CompressionType

Compressor library. For LZ4_FRAME, each compressed buffer must consist of a single frame.

pub fn method(&self) -> BodyCompressionMethod

Indicates the way the record batch body was compressed

Trait Implementations

impl<'a> Clone for BodyCompression<'a>

fn clone(&self) -> BodyCompression<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BodyCompression<'_>

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

Formats the value using the given formatter.

impl<'a> Follow<'a> for BodyCompression<'a>

type Inner = BodyCompression<'a>

unsafe fn follow( buf: &'a [u8], loc: usize, ) -> <BodyCompression<'a> as Follow<'a>>::Inner

Safety

impl<'a> PartialEq for BodyCompression<'a>

fn eq(&self, other: &BodyCompression<'a>) -> 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 Verifiable for BodyCompression<'_>

fn run_verifier( v: &mut Verifier<'_, '_>, pos: usize, ) -> Result<(), InvalidFlatbuffer>

Runs the verifier for this type, assuming its at position pos in the verifier’s buffer. Should not need to be called directly.
