Struct Retry

source 
pub struct Retry<'a> {
    gctx: &'a GlobalContext,
    retries: u64,
    max_retries: u64,
}
Expand description

State for managing retrying a network operation.

Fields§

§gctx: &'a GlobalContext§retries: u64

The number of failed attempts that have been done so far.

Starts at 0, and increases by one each time an attempt fails.

§max_retries: u64

The maximum number of times the operation should be retried.

0 means it should never retry.

Implementations§

source§

impl<'a> Retry<'a>

source

pub fn new(gctx: &'a GlobalContext) -> CargoResult<Retry<'a>>

source

pub fn try<T>(&mut self, f: impl FnOnce() -> CargoResult<T>) -> RetryResult<T>

Calls the given callback, and returns a RetryResult which indicates whether or not this needs to be called again at some point in the future to retry the operation if it failed.

source

fn next_sleep_ms(&self) -> u64

Gets the next sleep duration in milliseconds.

Layout§

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
