Enum MetadataCompression 

#[non_exhaustive]
pub enum MetadataCompression {
    BincodeStandard,
    Flate2,
}

Supported compression methods for FileFlags and BlockFlags.

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.

BincodeStandard

Bincode without compression.

Flate2

Gz compression with flate2.

Implementations

impl MetadataCompression

pub fn from_u8(val: u8) -> Result<Self, Box<dyn Error>>

Convert the u8 value stored in FileHeader or BlockHeader into a valid MetadataCompression.

Errors

Returns InvalidConversion if the u8 value does not correspond to a valid MetadataCompression.

Usage

use ahda::compression::MetadataCompression;
let u8_rep = 1_u8;
let compression_type = MetadataCompression::from_u8(u8_rep).unwrap();
assert_eq!(compression_type, MetadataCompression::Flate2);

pub fn to_u8(&self) -> u8

Convert a MetadataCompression into a u8 value for storage in FileHeader or BlockHeader.

Usage

use ahda::compression::MetadataCompression;
let compression_type = MetadataCompression::Flate2;
let u8_rep = compression_type.to_u8();
assert_eq!(u8_rep, 1_u8);
