Implementations§
source§impl Payload
impl Payload
sourcepub fn select(&self) -> Option<impl Iterator<Item = HashMap<&str, &Value>>>
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
