Trait Implementations

impl ApiCall<DatasetMetadata> for DatasetMetadataQuery

fn send(&self) -> Result<DatasetMetadata>

Submit a request to the Quandl’s API and return a parsed object representing the data received in a Rust-friendly format.

fn fmt_prefix(&self) -> Option<String>

If applicable, returns the string that would be appended between the QUANDL_API_URL and the ‘?’ character in a query URL.

fn fmt_arguments(&self) -> Option<String>

If applicable, returns the string that would be appended after the ‘?’ character in a query URL.

fn url(&self) -> String

Returns the URL that will be used to submit the query through Quandl’s API.

fn encoded_data(&self) -> Result<Vec<u8>>

Bypass the parsers and retrieve the byte stream received from Quandl directly.

impl Clone for DatasetMetadata

fn clone(&self) -> DatasetMetadata

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DatasetMetadata

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DatasetMetadata

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for DatasetMetadata

fn eq(&self, other: &DatasetMetadata) -> 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 Serialize for DatasetMetadata

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl StructuralPartialEq for DatasetMetadata
