Enum Retention 

pub enum Retention {
    Discard,
    Volatile {
        expiry: Option<Duration>,
    },
    Stored {
        expiry: Option<Duration>,
    },
}

Defines the retention of a data stream.

Describes what to do with the sent data if the transport is incapable of delivering it.

See Retention for more information.

Variants

Discard

Data is discarded.

Volatile

Data is kept in a cache in memory.

Fields

expiry: Option<Duration>

Duration for the data to expire.

If it’s None it will never expire.

Stored

Data is kept on disk.

Fields

expiry: Option<Duration>

Duration for the data to expire.

If it’s None it will never expire.

Implementations

impl Retention

pub const fn is_stored(&self) -> bool

Returns true if the retention is Stored.

pub const fn as_expiry(&self) -> Option<&Duration>

Returns the expiry for the retention.

For the Discard will always return None, while for Volatile or Stored returns the inner expiry only if set.

pub fn as_expiry_seconds(&self) -> Option<i64>

Returns the expiry for the retention in seconds.

For the Discard will always return None, while for Volatile or Stored returns the inner expiry only if set.

pub const fn is_volatile(&self) -> bool

Returns true if the retention is Volatile.

pub const fn is_discard(&self) -> bool

Returns true if the retention is Discard.

Trait Implementations

impl Clone for Retention

fn clone(&self) -> Retention

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Retention

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

Formats the value using the given formatter.

impl Default for Retention

fn default() -> Retention

Returns the “default value” for a type.

impl From<Retention> for Retention

fn from(value: Retention) -> Self

Converts to this type from the input type.

impl PartialEq for Retention

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