Struct ScanFile 

pub struct ScanFile {
    pub path: String,
    pub size: i64,
    pub modification_time: i64,
    pub stats: Option<Stats>,
    pub dv_info: DvInfo,
    pub transform: Option<ExpressionRef>,
    pub partition_values: HashMap<String, String>,
}

A ScanFile represents information about one file that needs to be scanned to read a table.

Fields

path: String

Path to the file

size: i64

Size of the file

modification_time: i64

The time the file was created, as milliseconds since the epoch

stats: Option<Stats>

Statistics about the file

dv_info: DvInfo

A DvInfo struct, which allows getting the selection vector for this file

transform: Option<ExpressionRef>

An optional expression that, if present, must be applied to physical data to convert it to the correct logical format

partition_values: HashMap<String, String>

a HashMap<String, String> which map partition names to the value they have in this file

Trait Implementations

impl Clone for ScanFile

fn clone(&self) -> ScanFile

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ScanFile

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

Formats the value using the given formatter.

impl PartialEq for ScanFile

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