Enum UpdateMode 

pub enum UpdateMode {
    FetchIfMissing,
    TryFetchIfOlderThan(u64),
    TryFetchLatest,
    FetchLatest,
}

An interface to facilitate direct programatic management of a catalog, usually as a local mirror of one or more remote catalogs used by a user to insulate them from upstream changes Indicates the desired behavior for updating the locally-cached module

Variants

FetchIfMissing

Fetches the module if it doesn’t exist, otherwise leaves it alone

TryFetchIfOlderThan(u64)

Attempts to fetch from the remote catalog is the local cached version is older than the specified number of seconds. Otherwise continues with the cached mod

TryFetchLatest

Attempts to fetch from the remote catalog. Continues with the existing module if the remote is unavailable

FetchLatest

Fetches the latest from the remote catalog. Fails if the remote is unavailable

Implementations

impl UpdateMode

pub fn promote_to(self, other: Self) -> Self

Returns the more aggressive (more likely to fetch) of the two modes

Trait Implementations

impl Clone for UpdateMode

fn clone(&self) -> UpdateMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UpdateMode

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

Formats the value using the given formatter.

impl PartialEq for UpdateMode

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