Struct RemoveMessage 

pub struct RemoveMessage {
    pub id: String,
}

Marker that requests deletion of a specific message from a conversation history. Tagged with the target message’s ID so reducers (e.g. merge_message_history) can locate and drop it.

Fields

id: String

Stable ID of the message to remove. Use Some("__all__") to clear the entire history.

Implementations

impl RemoveMessage

pub const ALL: &'static str = "__all__"

Sentinel ID meaning “remove every message in the history”.

pub fn new(id: impl Into<String>) -> Self

Build a RemoveMessage for a specific message ID.

pub fn all() -> Self

Build a RemoveMessage that clears the whole history.

pub fn is_all(&self) -> bool

True if this marker requests clearing the entire history.

Trait Implementations

impl Clone for RemoveMessage

fn clone(&self) -> RemoveMessage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RemoveMessage

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for RemoveMessage

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for RemoveMessage

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for RemoveMessage

fn eq(&self, other: &RemoveMessage) -> 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 Serialize for RemoveMessage

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
