Struct icu_datetime::fieldsets::serde::CompositeFieldSetSerde

source ยท
pub struct CompositeFieldSetSerde { /* private fields */ }
Expand description

๐Ÿšง [Experimental] A type corresponding to CompositeFieldSet that implements serde::Serialize and serde::Deserialize.

The serialized representation is subject to change.

๐Ÿšง This code is experimental; it may change at any time, in breaking or non-breaking ways, including in SemVer minor releases. Use with caution. #5825

ยงExamples

use icu::datetime::fieldsets;
use icu::datetime::fieldsets::enums::CompositeFieldSet;
use icu::datetime::fieldsets::enums::DateFieldSet;
use icu::datetime::fieldsets::serde::CompositeFieldSetSerde;

let field_set =
    CompositeFieldSet::Date(DateFieldSet::YMD(fieldsets::YMD::short()));
let serde_input = CompositeFieldSetSerde::from(field_set);

let json_string = serde_json::to_string(&serde_input).unwrap();
assert_eq!(
    json_string,
    r#"{"fieldSet":["year","month","day"],"length":"short"}"#
);

let serde_output =
    serde_json::from_str::<CompositeFieldSetSerde>(&json_string).unwrap();
let deserialized = CompositeFieldSet::try_from(serde_output).unwrap();

assert_eq!(field_set, deserialized);

If the field set is invalid, an error will occur:

use icu::datetime::fieldsets::enums::CompositeFieldSet;
use icu::datetime::fieldsets::serde::CompositeFieldSetSerde;
use icu::datetime::fieldsets::serde::CompositeFieldSetSerdeError;

let json_string = r#"{"fieldSet":["year","time"],"length":"short"}"#;
let serde_output =
    serde_json::from_str::<CompositeFieldSetSerde>(&json_string).unwrap();

assert!(matches!(
    CompositeFieldSet::try_from(serde_output),
    Err(CompositeFieldSetSerdeError::InvalidFields)
));
