Enum BitfieldEncoding 

pub enum BitfieldEncoding {
    Signed(u8),
    Unsigned(u8),
}

Encodes data into binary format. Bitfield integer encoding type supporting signed and unsigned bit widths. BITFIELD 整数类型编码（对标 Apache Kvrocks BitfieldEncoding）

Variants

Signed(u8)

Unsigned(u8)

Implementations

impl BitfieldEncoding

pub fn signed(bits: u8) -> Result<Self>

pub fn unsigned(bits: u8) -> Result<Self>

pub const fn is_signed(&self) -> bool

pub const fn is_unsigned(&self) -> bool

pub const fn bits(&self) -> u8

pub fn positional_offset(&self, index: u64) -> Result<u64>
