Struct QueuePolicy 

pub struct QueuePolicy {
    pub capacity: u32,
    pub drop_policy: DropPolicy,
    pub block_duration: u64,
    pub buffer_enabled: bool,
    pub buffer_capacity: u32,
    pub buffer_expire_ms: u64,
}

Northward envelope protocol types (re-exported at crate root).

Fields

capacity: u32

drop_policy: DropPolicy

block_duration: u64

buffer_enabled: bool

Enable buffer queue for unconnected state

buffer_capacity: u32

Buffer queue capacity (max number of items to buffer)

buffer_expire_ms: u64

Buffer expiration time in milliseconds (0 means no expiration)

Trait Implementations

impl Clone for QueuePolicy

fn clone(&self) -> QueuePolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QueuePolicy

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for QueuePolicy

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<QueuePolicy> for Value

fn from(source: QueuePolicy) -> Self

Converts to this type from the input type.

impl IntoActiveValue<QueuePolicy> for QueuePolicy

fn into_active_value(self) -> ActiveValue<QueuePolicy>

Method to perform the conversion

impl Nullable for QueuePolicy

fn null() -> Value

impl PartialEq for QueuePolicy

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

impl Serialize for QueuePolicy

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryGetableFromJson for QueuePolicy

fn try_get_from_json<I>(res: &QueryResult, idx: I) -> Result<Self, TryGetError>

where I: ColIdx,

Get a JSON from the query result with prefixed column name

fn from_json_vec(value: Value) -> Result<Vec<Self>, TryGetError>

Get a Vec from an Array of Json

impl ValueType for QueuePolicy

fn try_from(v: Value) -> Result<Self, ValueTypeErr>

fn type_name() -> String

fn array_type() -> ArrayType

fn column_type() -> ColumnType

fn unwrap(v: Value) -> Self

fn expect(v: Value, msg: &str) -> Self

fn is_option() -> bool

fn enum_type_name() -> Option<&'static str>
