Struct MmapVectorFile 

pub struct MmapVectorFile {
    pub mmap: MmapMut,
    pub header: VecFileHeader,
    pub path: PathBuf,
}

A memory-mapped file containing fixed-size raw f32 vectors.

Fields

mmap: MmapMut

Writable mmap covering the full file.

header: VecFileHeader

Decoded file header.

path: PathBuf

File path on disk.

Implementations

impl MmapVectorFile

pub fn create( path: &Path, dimensions: usize, max_elements: usize, ) -> VectorResult<Self>

Create a new vector file with capacity for max_elements vectors.

pub fn open(path: &Path) -> VectorResult<Self>

Open an existing vector file and validate its header.

pub fn write_vector( &mut self, internal_id: usize, vector: &[f32], ) -> VectorResult<()>

Write a vector to a fixed slot, updating the element count if needed.

pub fn read_vector(&self, internal_id: usize) -> VectorResult<Vec<f32>>

Read a vector from a fixed slot.

pub fn delete_vector(&mut self, internal_id: usize) -> VectorResult<()>

Zero out a vector slot without changing the file capacity.

pub fn flush(&self) -> VectorResult<()>

Flush pending changes to disk.

pub fn element_count(&self) -> usize

Return the number of written slots tracked in the header.

pub fn dimensions(&self) -> usize

Return the dimensionality of vectors stored in the file.

pub fn file_size_bytes(&self) -> u64

Return the total file size in bytes.
