Struct MetadataMessage

pub struct MetadataMessage {
    pub meta: Option<Meta>,
    pub data: Option<Data>,
    pub errors: Option<Vec<StatusMessage>>,
    pub other: Option<HashMap<String, Value>>,
}

The top-level type of a JSON file that conforms to the SDMX-JSON Metadata Message format.

Deserializing

From a string

use std::str::FromStr;
use std::fs::read_to_string;
use sdmx_json::metadata::MetadataMessage;

fn main() -> Result<(), Box<dyn std::error::Error + 'static>> {
    let file = read_to_string("sdmx-data.json")?;
    let message = MetadataMessage::from_str(file.as_str())?;
    Ok(())
}

From a byte slice

use std::fs::read;
use sdmx_json::metadata::MetadataMessage;

fn main() -> Result<(), Box<dyn std::error::Error + 'static>> {
    let file = read("sdmx-data.json")?;
    let message = MetadataMessage::try_from(file.as_slice())?;
    Ok(())
}

From a serde_json::Value

use serde_json::json;
use sdmx_json::metadata::MetadataMessage;

fn main() -> Result<(), Box<dyn std::error::Error + 'static>> {
    let value = json!({}); // assuming this has content
    let message = MetadataMessage::try_from(value);
    Ok(())
}

Trait Implementations

impl Clone for MetadataMessage

fn clone(&self) -> MetadataMessage

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MetadataMessage

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

Formats the value using the given formatter.

impl Default for MetadataMessage

fn default() -> MetadataMessage

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for MetadataMessage

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Extendable for MetadataMessage

fn other(&self) -> Option<&HashMap<String, Value>>

impl FromStr for MetadataMessage

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl PartialEq for MetadataMessage

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl SdmxMessage for MetadataMessage

type Data = Data

fn meta(&self) -> Option<&Meta>

fn data(&self) -> Option<&Self::Data>

fn errors(&self) -> Option<&Vec<StatusMessage>>

impl Serialize for MetadataMessage

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<'a> TryFrom<&'a [u8]> for MetadataMessage

type Error = Error

The type returned in the event of a conversion error.

fn try_from(slice: &'a [u8]) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<Value> for MetadataMessage

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: Value) -> Result<Self, Self::Error>

Performs the conversion.
