Implementations

impl Payload

pub fn select(&self) -> Option<impl Iterator<Item = HashMap<&str, &Value>>>

Exports select payloads as an std::iter::Iterator.

The items of the Iterator are HashMap<Column, Value>, and they are borrowed by default. If ownership is required, you need to acquire them directly.

• Some: Payload::Select, Payload::SelectMap
• None: otherwise

Trait Implementations

impl Clone for Payload

fn clone(&self) -> Payload

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Payload

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Payload

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Payload

fn eq(&self, other: &Payload) -> 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 SelectExt for Payload

fn rows_as<T: FromGlueRow>(self) -> Result<Vec<T>, RowConversionError>

fn one_as<T: FromGlueRow>(self) -> Result<T, RowConversionError>

impl Serialize for Payload

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
