Struct Mutation 

pub struct Mutation { /* private fields */ }

A logical mutation: reuse the same value after an uncertain response so the API applies the write once (Idempotency-Key), optionally with If-Match.

Implementations

impl Mutation

pub fn new() -> Self

A new logical write with a random key.

pub fn with_key(key: impl Into<String>) -> Result<Self, Error>

A logical write with your own key (8–255 visible ASCII characters).

pub fn if_match(self, version: i64) -> Result<Self, Error>

Applies the write only if the resource is still at version (If-Match).

pub fn key(&self) -> &str

The idempotency key.

Trait Implementations

impl Clone for Mutation

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Mutation

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

Formats the value using the given formatter.

impl Default for Mutation

fn default() -> Self

Returns the “default value” for a type.
