Implementations

impl PresenceState

pub fn as_str(&self) -> &'static str

pub fn priority(&self) -> u8

Priority for conflict resolution when a location appears as both src and dest for the same file. Higher value wins.

Failed > Syncing > Pending > Present > Absent

pub fn from_transfer(transfer: &Transfer, policy: &RetryPolicy) -> Self

Transfer + RetryPolicy からPresenceStateを導出。

Trait Implementations

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PresenceState

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,
