Struct MetadataKeyValuePair 

#[non_exhaustive]
pub struct MetadataKeyValuePair {
    pub metadata_key: Option<String>,
    pub metadata_value: Option<String>,
}

A structure containing a key value pair for metadata.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

metadata_key: Option<String>

A metadata key.

metadata_value: Option<String>

A metadata key’s corresponding value.

Implementations

impl MetadataKeyValuePair

pub fn metadata_key(&self) -> Option<&str>

A metadata key.

pub fn metadata_value(&self) -> Option<&str>

A metadata key’s corresponding value.

impl MetadataKeyValuePair

pub fn builder() -> MetadataKeyValuePairBuilder

Creates a new builder-style object to manufacture MetadataKeyValuePair.

Trait Implementations

impl Clone for MetadataKeyValuePair

fn clone(&self) -> MetadataKeyValuePair

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MetadataKeyValuePair

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

Formats the value using the given formatter.

impl PartialEq for MetadataKeyValuePair

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