Struct CompressedVectorView 

pub struct CompressedVectorView<'a> {
    pub format_version: u8,
    pub config_hash: &'a str,
    pub dimension: u32,
    pub bit_width: u8,
    pub packed_indices: &'a [u8],
    pub residual: Option<&'a [u8]>,
}

A zero-copy view of a single Level-1 serialized CompressedVector.

All fields borrow from the input byte slice. No heap allocation occurs during parse or unpack_into.

fn assert_not_serialize<T: serde::Serialize>() {}
assert_not_serialize::<tinyquant_io::CompressedVectorView<'_>>();

Fields

format_version: u8

Format version byte from the Level-1 header.

config_hash: &'a str

Config hash string borrowed from the Level-1 header.

dimension: u32

Number of dimensions.

bit_width: u8

Bit width (2, 4, or 8).

packed_indices: &'a [u8]

Packed index bytes (LSB-first).

residual: Option<&'a [u8]>

Residual bytes (2 bytes per dimension), or None.

Implementations

impl<'a> CompressedVectorView<'a>

pub fn parse(data: &'a [u8]) -> Result<(Self, &'a [u8]), IoError>

Parse a single Level-1 record from the start of data.

Returns (view, unconsumed_tail).

Errors

Returns IoError if the data is truncated, has an unknown version, an invalid bit-width, or a bad residual flag.

pub fn unpack_into(&self, out: &mut [u8]) -> Result<(), IoError>

Unpack indices into caller-provided buffer (no allocation).

Errors

Returns IoError::LengthMismatch if out.len() != self.dimension as usize.

pub fn to_owned_cv(&self) -> Result<CompressedVector, IoError>

Allocating escape hatch — copies borrowed bytes into an owned CompressedVector.

Errors

Returns IoError if unpacking or construction fails.
