Struct DownloadSchedule 

pub struct DownloadSchedule {
    attempts: NonZeroU32,
    initial_delay: Duration,
    parallelism: NonZeroU8,
}

Configuration for how many times to retry a download, with what frequency.

Fields

attempts: NonZeroU32

How many attempts to make before giving up?

initial_delay: Duration

The amount of time to delay after the first failure, and a lower-bound for future delays.

parallelism: NonZeroU8

When we want to download a bunch of these at a time, how many attempts should we try to launch at once?

Implementations

impl DownloadSchedule

pub fn builder() -> DownloadScheduleBuilder

Return a new [DownloadSchedule Builder] to construct an instance of this type.

impl DownloadSchedule

pub fn attempts(&self) -> impl Iterator<Item = u32> + use<>

Return an iterator to use over all the supported attempts for this configuration.

pub fn n_attempts(&self) -> u32

Return the number of times that we’re supposed to retry, according to this DownloadSchedule.

pub fn parallelism(&self) -> u8

Return the number of parallel attempts that we’re supposed to launch, according to this DownloadSchedule.

pub fn schedule(&self) -> RetryDelay

Return a RetryDelay object for this configuration.

If the initial delay is longer than 32

Trait Implementations

impl Buildable for DownloadSchedule

type Builder = DownloadScheduleBuilder

The type that constructs this Buildable.

fn builder() -> DownloadScheduleBuilder

Return a new Builder for this type.

impl Clone for DownloadSchedule

fn clone(&self) -> DownloadSchedule

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DownloadSchedule

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

Formats the value using the given formatter.

impl Default for DownloadSchedule

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for DownloadSchedule

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