Module arrow::ipc::gen::Message [−][src]
Structs
Optional compression for the memory buffers constituting IPC message bodies. Intended for use with RecordBatch but could be used for other message types
Provided for forward compatibility in case we need to support different strategies for compressing the IPC message body (like whole-body compression rather than buffer-level) in the future
For sending dictionary encoding information. Any Field can be dictionary-encoded, but in this case none of its children may be dictionary-encoded. There is one vector / column per dictionary, but that vector / column may be spread across multiple dictionary batches by using the isDelta flag
A data header describing the shared memory layout of a “record” or “row” batch. Some systems call this a “row batch” internally and others a “record batch”.

Verifies that a buffer of bytes contains a Message
and returns it.
Note that verification is still experimental and may not
catch every error, or be maximally performant. For the
previous, unchecked, behavior use
root_as_message_unchecked
.
Assumes, without verification, that a buffer of bytes contains a Message and returns it.
Verifies, with the given options, that a buffer of bytes
contains a Message
and returns it.
Note that verification is still experimental and may not
catch every error, or be maximally performant. For the
previous, unchecked, behavior use
root_as_message_unchecked
.
Verifies that a buffer of bytes contains a size prefixed
Message
and returns it.
Note that verification is still experimental and may not
catch every error, or be maximally performant. For the
previous, unchecked, behavior use
size_prefixed_root_as_message_unchecked
.
Assumes, without verification, that a buffer of bytes contains a size prefixed Message and returns it.
Verifies, with the given verifier options, that a buffer of
bytes contains a size prefixed Message
and returns
it. Note that verification is still experimental and may not
catch every error, or be maximally performant. For the
