Struct NdefRecord 

pub struct NdefRecord {
    pub record_type: String,
    pub media_type: Option<String>,
    pub id: Option<String>,
    pub encoding: Option<String>,
    pub lang: Option<String>,
    pub data: Option<String>,
    pub data_base64: Option<Bytes>,
}

One NDEF record, as Web NFC’s NDEFRecordInit.

use hardless_core::NdefRecord;
let text: NdefRecord =
    serde_json::from_str(r#"{ "recordType": "text", "data": "Hello", "lang": "en" }"#).unwrap();
assert_eq!(text.payload(), b"Hello");
let png: NdefRecord = serde_json::from_str(
    r#"{ "recordType": "mime", "mediaType": "image/png", "dataBase64": "iVBORw==" }"#,
).unwrap();
assert_eq!(png.payload(), b"\x89PNG");
assert!(text.validate().is_ok() && png.validate().is_ok());

Fields

record_type: String

empty, text, url, absolute-url, mime, unknown, or an external type such as example.com:loyalty.

media_type: Option<String>

The MIME type of a mime record, e.g. application/json.

id: Option<String>

The record identifier.

encoding: Option<String>

The text encoding of a text record: utf-8 (default), utf-16, utf-16be or utf-16le.

lang: Option<String>

The language of a text record, e.g. en.

data: Option<String>

A text payload: the text of a text record, the URL of a url record, or any payload that is UTF-8 text.

data_base64: Option<Bytes>

A binary payload, base64. At most one of data and dataBase64 is set.

Implementations

impl NdefRecord

pub fn text(text: impl Into<String>) -> Self

A text record.

assert_eq!(hardless_core::NdefRecord::text("Hi").record_type, "text");

pub fn url(url: impl Into<String>) -> Self

A url record.

pub fn payload(&self) -> Vec<u8>

The payload bytes: data as UTF-8, or the decoded dataBase64.

pub fn validate(&self) -> Result<(), String>

Checks the record the way Web NFC checks an NDEFRecordInit before writing it.

Trait Implementations

impl Clone for NdefRecord

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for NdefRecord

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for NdefRecord

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for NdefRecord

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for NdefRecord

impl JsonSchema for NdefRecord

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl PartialEq for NdefRecord

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl Serialize for NdefRecord

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
