Struct nature_common::MetaSetting

pub struct MetaSetting {
    pub is_state: bool,
    pub master: Option<String>,
    pub multi_meta: BTreeSet<String>,
    pub cache_saved: bool,
    pub only_one: bool,
}

Fields

is_state: bool

master: Option<String>

Only useful for state-meta. A meta_string, this meta instance's id will use its master instance's id. As a target meta, if no executor appointed. an auto-converter will be created.

multi_meta: BTreeSet<String>

MetaSettingTemp#multi_meta can't use BTreeSet type, so make this struct for it, it would be good performance for multi_meta verify. each of the item's format is meta-type:business-key:version

cache_saved: bool

Nature will cache the saved instance for a while, this can increase performance greatly to save same instance, such as to generate a timer instance.

only_one: bool

only used by MetaType::Loop, has only one instance generated when loop finished. Requirement: multi_meta should has only one item

Trait Implementations

impl Clone for MetaSetting

fn clone(&self) -> MetaSetting

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MetaSetting

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

Formats the value using the given formatter.

impl Default for MetaSetting

fn default() -> MetaSetting

Returns the "default value" for a type.

impl<'de> Deserialize<'de> for MetaSetting

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where
    __D: Deserializer<'de>,

impl Eq for MetaSetting

impl FromStr for MetaSetting

type Err = NatureError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self>

Parses a string s to return a value of this type.

impl Ord for MetaSetting

fn cmp(&self, other: &MetaSetting) -> Ordering

This method returns an [Ordering] between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl PartialEq<MetaSetting> for MetaSetting

fn eq(&self, other: &MetaSetting) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &MetaSetting) -> bool

This method tests for !=.

impl PartialOrd<MetaSetting> for MetaSetting

fn partial_cmp(&self, other: &MetaSetting) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &MetaSetting) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &MetaSetting) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &MetaSetting) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &MetaSetting) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
