Struct FileInfo 

pub struct FileInfo {
    pub filename: String,
    pub filetype: String,
    pub storage_format: String,
    pub rows: usize,
    pub cols: usize,
    pub nnz: Option<usize>,
    pub size_bytes: Option<u64>,
}

Represent a single file spec in the persistence directory

Fields

filename: String

name of the file, can be equal to filetype if there is only one per type

filetype: String

see Self::which_filetype(..): “rawinput” | “sub_centroids” | “lambdas” | “…”

storage_format: String

see Self::which_format(..)

rows: usize

cols: usize

nnz: Option<usize>

size_bytes: Option<u64>

Implementations

impl FileInfo

pub fn new( filename: String, filetype: &str, data_shape: (usize, usize), nnz: Option<usize>, size_bytes: Option<u64>, ) -> StorageResult<Self>

Create a file spec to add to the persistence directory

Fails with StorageError::UnsupportedFormat for unrecognised filetypes instead of panicking (issue #45).

pub fn which_format(filetype: &str) -> StorageResult<String>

Assign the right format to the file type

pub fn which_filetype(filetype: &str) -> StorageResult<String>

Assign the right filetype to the keyname of the file

Trait Implementations

impl Clone for FileInfo

fn clone(&self) -> FileInfo

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FileInfo

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FileInfo

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for FileInfo

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
