Enum compressed_vec::section::FixedSectEnum

pub enum FixedSectEnum<'buf, T: VectBase> {
    NullFixedSect(NullFixedSect),
    NibblePackMedFixedSect(NibblePackMedFixedSect<'buf, T>),
    DeltaNPMedFixedSect(DeltaNPMedFixedSect<'buf, T>),
    ConstFixedSect(ConstFixedSect<'buf, T>),
    XorNPMedFixedSect(XorNPMedFixedSect<'buf>),
}

A FixedSectEnum is an enum over different FixedSection implementations, for the purpose of very fast, inlineable iteration over different section types without resorting to dynamic method calls.

Variants

NullFixedSect(NullFixedSect)

NibblePackMedFixedSect(NibblePackMedFixedSect<'buf, T>)

DeltaNPMedFixedSect(DeltaNPMedFixedSect<'buf, T>)

ConstFixedSect(ConstFixedSect<'buf, T>)

XorNPMedFixedSect(XorNPMedFixedSect<'buf>)

Implementations

impl<'buf, T: VectBase> FixedSectEnum<'buf, T>

pub fn decode<S>(self, sink: &mut S) -> Result<(), CodingError> where
    S: Sink<T::SI>, 

Decodes this section based on items of type T to a Sink. This is the main decoding API. Note that you need to specify an explicit base type as FixedSectEnums are typeless. For example, to write to the generic section sink which materializes every value in a section:

    let sect = FixedSectEnum::<u32>::try_from(&sect_bytes[..]).unwrap();
    let mut sink = compressed_vec::sink::U32_256Sink::new();
    sect.decode(&mut sink).unwrap();
    println!("{:?}", sink.values.iter().count());

pub fn is_null(&self) -> bool

Is this a null section?
