Struct TlsMapDelta 

pub struct TlsMapDelta<K, V> {
    pub mutations: Vec<TlsMapMutation<K, V>>,
}

A list of mutations to apply atomically to a TlsMap.

Built with a fluent API and applied via TlsMap::apply_delta.

use xmtp_mls_common::tls_map::TlsMapDelta;

let delta = TlsMapDelta::<u8, u8>::new()
    .insert(1, 10)
    .update(2, 20)
    .delete(3);
assert_eq!(delta.mutations.len(), 3);

Fields

mutations: Vec<TlsMapMutation<K, V>>

The ordered list of mutations to apply.

Implementations

impl<K, V> TlsMapDelta<K, V>

pub fn new() -> Self

Create an empty delta with no mutations.

pub fn insert(self, key: K, value: V) -> Self

Append an insert mutation. Consumes and returns self for chaining.

pub fn update(self, key: K, value: V) -> Self

Append an update mutation. Consumes and returns self for chaining.

pub fn delete(self, key: K) -> Self

Append a delete mutation. Consumes and returns self for chaining.

Trait Implementations

impl<K: Clone, V: Clone> Clone for TlsMapDelta<K, V>

fn clone(&self) -> TlsMapDelta<K, V>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<K: Debug, V: Debug> Debug for TlsMapDelta<K, V>

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

Formats the value using the given formatter.

impl<K, V> Default for TlsMapDelta<K, V>

fn default() -> Self

Returns the “default value” for a type.

impl<K, V> Deserialize for TlsMapDelta<K, V>

where K: Deserialize + Size, V: Deserialize + Size,

fn tls_deserialize<R: Read>(bytes: &mut R) -> Result<Self, Error>

where Self: Sized,

This function deserializes the bytes from the provided a std::io::Read and returns the populated struct.

fn tls_deserialize_exact(bytes: impl AsRef<[u8]>) -> Result<Self, Error>

where Self: Sized,

This function deserializes the provided bytes and returns the populated struct. All bytes must be consumed.

impl<K: PartialEq, V: PartialEq> PartialEq for TlsMapDelta<K, V>

fn eq(&self, other: &TlsMapDelta<K, V>) -> 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<K: Serialize + Size + Debug, V: Serialize + Size + Debug> Serialize for TlsMapDelta<K, V>

fn tls_serialize<W: Write>(&self, writer: &mut W) -> Result<usize, Error>

Serialize self and write it to the writer. The function returns the number of bytes written to writer.

fn tls_serialize_detached(&self) -> Result<Vec<u8>, Error>

Serialize self and return it as a byte vector.

impl<K: Size, V: Size> Size for TlsMapDelta<K, V>

fn tls_serialized_len(&self) -> usize

impl<K: Eq, V: Eq> Eq for TlsMapDelta<K, V>
