Enum ValueFlag 

#[repr(u8)]
pub enum ValueFlag {
    Raw = 0,
    Lz4 = 1,
}

One-byte tag stored alongside the encoded payload. Distinguishes raw passthrough from compressed bytes so decode knows what to do without re-running compression.

Variants

Raw = 0

Payload bytes are the original input, byte-identical.

Lz4 = 1

Payload bytes are an LZ4 block; the original length is prepended as a little-endian u32 so decode can size the output buffer without a separate length sidecar.

Implementations

impl ValueFlag

pub fn from_byte(b: u8) -> Result<ValueFlag, ValueCodecError>

Convert from the on-disk tag byte. Unknown tags are rejected.

Trait Implementations

impl Clone for ValueFlag

fn clone(&self) -> ValueFlag

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ValueFlag

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl PartialEq for ValueFlag

fn eq(&self, other: &ValueFlag) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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