Enum BitmapType 

#[non_exhaustive]
pub enum BitmapType {
    Roaring32,
    Roaring64,
}

Supported bitmap types for an .ahda record

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Roaring32

RoaringBitmap (32-bit address space)

Roaring64

RoaringTreemap (64-bit address space)

Implementations

impl BitmapType

pub fn from_u16(val: u16) -> Result<Self, Box<dyn Error>>

Convert the u16 value stored in FileHeader or BlockHeader into a valid BitmapType.

Errors

Returns InvalidConversion if the u16 value does not correspond to a valid BitmapType.

Usage

use ahda::compression::BitmapType;
let u16_rep = 0_u16;
let bitmap_type = BitmapType::from_u16(u16_rep).unwrap();
assert_eq!(bitmap_type, BitmapType::Roaring32);

pub fn to_u16(&self) -> u16

Convert a BitmapType into a u16 value for storage in FileHeader or BlockHeader.

Usage

use ahda::compression::BitmapType;
let bitmap_type = BitmapType::Roaring32;
let u16_rep = bitmap_type.to_u16();
assert_eq!(u16_rep, 0_u16);
