Struct Record 

pub struct Record {
    pub id: u64,
    pub fields: AHashMap<String, FieldValue>,
    pub source: Option<String>,
}

A single data record with a unique ID and a map of field values.

Fields

id: u64

fields: AHashMap<String, FieldValue>

source: Option<String>

Implementations

impl Record

pub fn new(id: u64) -> Record

pub fn with_source(self, source: impl Into<String>) -> Record

pub fn insert( self, name: impl Into<String>, value: impl Into<FieldValue>, ) -> Record

pub fn get(&self, name: &str) -> Option<&FieldValue>

pub fn text(&self, name: &str) -> Option<&str>

pub fn field_as_str(&self, name: &str) -> Option<Cow<'_, str>>

Returns the field value as a string, coercing non-text scalars to their string representation.

pub fn field_as<T>(&self, name: &str) -> Option<T>

where T: FromFieldValue,

Extract a typed value from a named field using the FromFieldValue trait.

use zer_core::record::{Record, FieldValue};
let r = Record::new(1).insert("lat", 52.37f64);
let lat: Option<f64> = r.field_as::<f64>("lat");
assert_eq!(lat, Some(52.37));
