Struct IpcWriteContext 

pub struct IpcWriteContext {
    pub(crate) scratch: Vec<u8>,
    fbb: FlatBufferBuilder<'static>,
    compressor: Option<Compressor<'static>>,
}

Additional context that may be needed for compression.

In the case of zstd, this will contain the zstd context, which can be reused between subsequent compression calls to avoid the performance overhead of initialising a new context for every compression. Also holds a [FlatBufferBuilder] that is reused across IPC writes.

Fields

scratch: Vec<u8>

fbb: FlatBufferBuilder<'static>

compressor: Option<Compressor<'static>>

Implementations

impl IpcWriteContext

pub(crate) fn mut_fbb(&mut self) -> &mut FlatBufferBuilder<'static>
