[−][src]Module activitystreams::primitives
Types defined as 'primitives' are used as building-blocks for ActivityStreams objects.
For example, an Object
may have a summary
field, which is defined as a range of
xsd:string
and rdf:langString
. As code, this is represented as an enum that either
contains an XsdString
or an RdfLangString
.
use activitystreams::primitives::{RdfLangString, XsdString}; /// Define a terminating enum for the Summary field in Object Properties /// /// In this case, terminating means it does not contain child elements. pub enum ObjectPropertiesSummaryTermEnum { XsdString(XsdString), RdfLangString(RdfLangString), } /// Since summary isn't functional, we can either have a single string, or multiple strings. pub enum ObjectPropertiesSummaryEnum { Term(ObjectPropertiesSummaryTermEnum), Array(Vec<ObjectPropertiesSummaryTermEnum>), } /// Define an excerpt from the ObjectProperties struct pub struct ObjectProperties { // ... /// Since summary isn't a required field, it's stored as an option summary: Option<ObjectPropertiesSummaryEnum>, // ... }
Structs
MimeMediaType | A MIME Media Type consists of a top-level type and a subtype, which is further structured into trees. |
MimeMediaTypeError | The error type produced when a MimeMediaType cannot be parsed |
RdfLangString | The rdf.langString type extends xs.string, and represents a language tagged string in RDF. |
XsdAnyUri | The type xsd:anyURI represents a Uniform Resource Identifier (URI) reference. |
XsdAnyUriError | The error type produced when an XsdAnyUri cannot be parsed |
XsdDateTime | The type xsd:dateTime represents a specific date and time in the format CCYY-MM-DDThh:mm:ss.sss, which is a concatenation of the date and time forms, separated by a literal letter "T". |
XsdDateTimeError | The error type produced when an XsdDateTime cannot be parsed |
XsdDuration | The type xsd:duration represents a duration of time expressed as a number of years, months, days, hours, minutes, and seconds. |
XsdDurationError | The error type produced when an XsdDuration cannot be parsed |
XsdFloat | The type xsd:float represents an IEEE single-precision 32-bit floating-point number. |
XsdFloatError | The error type produced when an XsdFloat cannot be parsed |
XsdNonNegativeFloat | The type xsd:float represents an IEEE single-precision 32-bit floating-point number. |
XsdNonNegativeFloatError | The error type produced when an XsdNonNegativeFloat cannot be parsed |
XsdNonNegativeInteger | The type xsd:nonNegativeInteger represents an arbitrarily large non-negative integer. |
XsdNonNegativeIntegerError | The error type produced when an XsdNonNegativeInteger cannot be parsed |
XsdString | A string type that conforms to the xsd:string specification. |
Enums
Length | A list of units of length that represent valid units for certain ActivityStreams objects |
