Struct ChannelCursor 

pub struct ChannelCursor(/* private fields */);

Opaque cursor used by clients to resume channel delivery.

Cursors currently wrap the last seen event id. Clients should pass them back unchanged instead of interpreting them.

Implementations

impl ChannelCursor

pub fn new(id: ChannelEventId) -> Self

Creates a cursor after the given event id.

pub fn event_id(self) -> ChannelEventId

Returns the event id represented by this cursor.

Trait Implementations

impl Clone for ChannelCursor

fn clone(&self) -> ChannelCursor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ChannelCursor

impl Debug for ChannelCursor

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ChannelCursor

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ChannelCursor

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

Formats the value using the given formatter.

impl Eq for ChannelCursor

impl FromStr for ChannelCursor

type Err = ChannelError

The associated error which can be returned from parsing.

fn from_str(value: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl JsonSchema for ChannelCursor

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl PartialEq for ChannelCursor

fn eq(&self, other: &ChannelCursor) -> 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 ChannelCursor

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
