Struct Context 

pub struct Context(pub OneOrMany<ContextEntry>);

The value of a JSON-LD @context property.

May be a single entry (emitted as a bare value) or multiple entries (emitted as an array). The wire format is driven by OneOrMany.

Tuple Fields

0: OneOrMany<ContextEntry>

Implementations

impl Context

pub const AS2: &'static str = "https://www.w3.org/ns/activitystreams"

The canonical Activity Streams 2.0 context URI.

pub const CID_V1: &'static str = "https://www.w3.org/ns/cid/v1"

The Controlled Identifiers v1 context, required by FEP-521a.

pub const DATA_INTEGRITY_V2: &'static str = "https://w3id.org/security/data-integrity/v2"

The Data Integrity v2 context, required by FEP-8b32 proofs.

pub const SECURITY_V1: &'static str = "https://w3id.org/security/v1"

The legacy Security v1 context used by older Mastodon actors.

pub fn activitystreams() -> Self

Creates a Context containing only the canonical AS 2.0 URI.

pub fn activitystreams_security() -> Self

Creates a Context containing the AS 2.0 URI plus the Security v1 URI — the combination emitted by most current Fediverse actors.

pub fn activitystreams_integrity() -> Self

Creates a Context containing AS 2.0 plus the Data Integrity context — the combination required when emitting FEP-8b32 proofs.

pub fn entries(&self) -> &[ContextEntry]

Returns the entries of this context.

pub fn push(&mut self, entry: ContextEntry)

Appends an entry to this context.

pub fn contains(&self, uri: &str) -> bool

Returns true if the context contains the given URI.

Trait Implementations

impl Clone for Context

fn clone(&self) -> Context

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Context

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

Formats the value using the given formatter.

impl Default for Context

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Context

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for Context

impl From<Url> for Context

fn from(url: Url) -> Self

Converts to this type from the input type.

impl PartialEq for Context

fn eq(&self, other: &Context) -> 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 Context

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
