Struct Part 

pub(crate) struct Part {
    pub start: u64,
    pub end: Option<u64>,
    pub saved: u64,
    pub connection: Option<Live>,
    pub failures: u32,
    pub retry_at: Option<Instant>,
}

A stretch of the file, and how much of it is saved.

Fields

start: u64

end: Option<u64>

Where the next part starts; None for a part that runs to the end of the file.

saved: u64

The bytes saved from start on.

connection: Option<Live>

The connection fetching it, unless it is paused, waiting to retry, or done.

failures: u32

The failures in a row that may pass, since it last received data.

retry_at: Option<Instant>

When to try it again, after such a failure.

Implementations

impl Part

pub(crate) fn whole() -> Self

The whole file, as one connection fetches it.

pub(crate) fn position(&self) -> u64

Where in the file its next byte goes.

pub(crate) fn rest(&self) -> ByteRange

What is left of it to ask for.

pub(crate) fn room(&self) -> Option<u64>

How many more bytes it takes, when it ends before the file does.

pub(crate) fn is_complete(&self, total: Option<u64>) -> bool

Whether all of it is saved, given the whole file’s length when known.

pub(crate) fn hang_up(&mut self) -> Option<File>

Stops its connection, counting everything it wrote, and gives the file it was writing, if the server had answered.

Trait Implementations

impl Debug for Part

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

Formats the value using the given formatter.
