Enum FileSelection 

pub enum FileSelection {
    Single(usize),
    Range(usize, usize),
}

A file selection entry from a BEP 53 so= parameter.

Variants

Single(usize)

A single file index.

Range(usize, usize)

An inclusive range of file indices.

Implementations

impl FileSelection

pub fn parse(value: &str) -> Result<Vec<Self>, String>

Parse a so= parameter value into a list of file selections.

Format: comma-separated entries, each either a single index or start-end range. Example: "0,2,4-6" -> [Single(0), Single(2), Range(4, 6)]

Errors

Returns an error if the value is empty or contains invalid entries.

pub fn to_priorities(selections: &[Self], num_files: usize) -> Vec<FilePriority>

Convert file selections into a FilePriority vector.

Selected files get Normal priority, unselected get Skip. num_files is the total number of files in the torrent. Out-of-range selections are silently ignored.

pub fn to_so_value(selections: &[Self]) -> String

Serialize file selections back to a so= parameter value string.

Trait Implementations

impl Clone for FileSelection

fn clone(&self) -> FileSelection

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FileSelection

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

Formats the value using the given formatter.

impl PartialEq for FileSelection

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