Struct FileSlice 

pub struct FileSlice {
    pub base_file: BaseFile,
    pub log_files: BTreeSet<LogFile>,
    pub partition_path: String,
}

Within a crate::file_group::FileGroup, a FileSlice is a logical group of BaseFile and LogFiles.

Fields

base_file: BaseFile

log_files: BTreeSet<LogFile>

partition_path: String

Implementations

impl FileSlice

pub fn new(base_file: BaseFile, partition_path: String) -> FileSlice

pub fn has_log_file(&self) -> bool

pub fn merge(&mut self, other: &FileSlice) -> Result<(), CoreError>

pub fn base_file_relative_path(&self) -> Result<String, CoreError>

Returns the relative path of the BaseFile in the FileSlice.

pub fn log_file_relative_path( &self, log_file: &LogFile, ) -> Result<String, CoreError>

Returns the relative path of the given LogFile in the FileSlice.

pub fn file_id(&self) -> &str

Returns the enclosing [FileGroup]’s id.

pub fn creation_instant_time(&self) -> &str

Returns the instant time that marks the FileSlice creation.

This is also an instant time stored in the [Timeline].

pub async fn load_metadata_if_needed( &mut self, storage: &Storage, ) -> Result<(), CoreError>

Load [FileMetadata] from storage layer for the BaseFile if file_metadata is None or if file_metadata is not fully populated.

Trait Implementations

impl Clone for FileSlice

fn clone(&self) -> FileSlice

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FileSlice

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

Formats the value using the given formatter.

impl Display for FileSlice

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

Formats the value using the given formatter.

impl PartialEq for FileSlice

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