Represent a field value

Variants

Float(f64)

Tuple Fields

0: f64

Represent a floating point number field value

Integer(i64)

Tuple Fields

0: i64

Represent a signed integer number field value

UnsignedInteger(u64)

Tuple Fields

0: u64

Represent an unsigned integer number field value

String(String)

Tuple Fields

0: String

Represent a string field value

Boolean(bool)

Tuple Fields

0: bool

Represent a boolean field value

Timestamp(DateTime<Utc>)

Tuple Fields

0: DateTime<Utc>

Represent an instant field value

InfluxDB does not natively support instants as field values, so this is represented as a nanosecond timestamp.

Implementations

impl FieldValue

pub fn escape_to_line_protocol(&self) -> String

Escape a field value to InfluxDB line protocol

Numeric and boolean values are escaped as they are. Timestamps are converted to nanoseconds from epoch. Strings are enclosed in double quotes, and characters " and \ are escaped.

let mut value = FieldValue::String("a string \"value\"".into());
assert_eq!(value.escape_to_line_protocol(), "\"a string \\\\\"value\\\\\"\"".to_string());
