Struct FileMetadata 

pub struct FileMetadata {
    pub hashes: Hashes,
    pub size: u64,
    pub created_by: String,
    pub add_time: Timestamp,
    pub compression: Compression,
    pub message: Option<String>,
}

The dvs metadata for a given file

Fields

hashes: Hashes

size: u64

created_by: String

add_time: Timestamp

compression: Compression

message: Option<String>

Implementations

impl FileMetadata

pub fn from_hashes( hashes: Hashes, size: u64, compression: Compression, message: Option<String>, ) -> Self

pub fn from_file( path: impl AsRef<Path>, compression: Compression, message: Option<String>, ) -> Result<Self>

pub fn save( &self, operation_id: Uuid, source_file: impl AsRef<Path>, backend: &dyn Backend, paths: &DvsPaths, relative_path: impl AsRef<Path>, on_bytes: Option<&(dyn Fn(u64) + Send + Sync)>, ) -> Result<(Outcome, Option<u64>)>

Returns whether the file already existed in the dvs folder and therefore is an update and the compressed size if applicable. Copies the source file to storage and saves metadata atomically (both succeed or neither).

Trait Implementations

impl Clone for FileMetadata

fn clone(&self) -> FileMetadata

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FileMetadata

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FileMetadata

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for FileMetadata

fn eq(&self, other: &Self) -> 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.

impl Serialize for FileMetadata

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
