Implementations

impl PeekNotification

fn new( peek_response: &PeekResponse, offset: usize, limit: Option<usize>, ) -> Self

Construct a new PeekNotification from a PeekResponse. The offset and limit parameters are used to calculate the number of rows in the peek result.

Trait Implementations

impl Clone for PeekNotification

fn clone(&self) -> PeekNotification

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PeekNotification

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PeekNotification

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for PeekNotification

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
