Value represents the value of a any field. It is an enum over all over all of the possible field type.

Variants

Str(String)

The str type is used for any text information.

U64(u64)

Unsigned 64-bits Integer u64

I64(i64)

Signed 64-bits Integer i64

F64(f64)

64-bits Float f64

Date(DateTime)

Signed 64-bits Date time stamp date

Facet(Facet)

Hierarchical Facet

Bytes(Vec<u8>)

Arbitrarily sized byte array

Methods

impl Value

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

Returns the text value, provided the value is of the Str type. (Returns None if the value is not of the Str type).

pub fn u64_value(&self) -> u64

Returns the u64-value, provided the value is of the U64 type.

Panics

If the value is not of type U64

pub fn i64_value(&self) -> i64

Returns the i64-value, provided the value is of the I64 type.

Panics

If the value is not of type I64

pub fn f64_value(&self) -> f64

Returns the f64-value, provided the value is of the F64 type.

Panics

If the value is not of type F64

pub fn date_value(&self) -> &DateTime

Returns the Date-value, provided the value is of the Date type.

Panics

If the value is not of type Date
