Struct BodyCompression

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

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

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

Source§

fn eq(&self, other: &BodyCompression<'a>) -> bool

1.0.0 · Source§

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
