Struct nature_common::Meta

pub struct Meta {
    pub version: u32,
    // some fields omitted
}

separator for Meta's key Business Metadata

Fields

version: u32

A Meta can be changed in future, the version will support this without effect the old ones

Implementations

impl Meta

pub fn key_standardize(biz: &str) -> Result<String>

make start with "/" and remove "/" at the end

pub fn new(key: &str, version: u32, meta_type: MetaType) -> Result<Self>

pub fn get_key(&self) -> String

pub fn get_meta_type(&self) -> MetaType

pub fn set_meta_type(&mut self, meta_type: MetaType)

pub fn from_string(meta_str: &str) -> Result<Meta>

meta_str's format : MetaType:[key]:[version]

Trait Implementations

impl Clone for Meta

fn clone(&self) -> Meta

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Meta

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

Formats the value using the given formatter.

impl Default for Meta

fn default() -> Self

Returns the "default value" for a type.

impl Eq for Meta

impl Ord for Meta

fn cmp(&self, other: &Meta) -> 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<Meta> for Meta

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

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

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

This method tests for !=.

impl PartialOrd<Meta> for Meta

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

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

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

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

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

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

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

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

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

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