Struct activitystreams::link::LinkBox

pub struct LinkBox(_);

A wrapper type around a generic Link

Implementations

impl LinkBox

pub fn from_concrete<T>(t: T) -> Result<Self, Error> where
    T: Link + Serialize, 

Coerce a concrete type into this wrapper type

This is done automatically via TryFrom in proprties setter methods

pub fn into_concrete<T>(self) -> Result<T, Error> where
    T: Link + DeserializeOwned, 

Attempt to deserialize the wrapper type to a concrete type

Before this method is called, the type should be verified via the kind or is_kind methods

pub fn is_kind(&self, kind: impl Display) -> bool

Return whether the given wrapper type is expected.

For example

use activitystreams::object::{
    kind::ImageType,
    apub::Image,
};
if my_wrapper_type.is_kind(ImageType) {
    let image = my_wrapper_type.into_concrete::<Image>()?;
    ...
}

pub fn kind(&self) -> Option<&str>

Return the kind of wrapper type, if present

Example

match my_wrapper_type.kind() {
    Some("Image") => {
        let image = my_wrapper_type.into_concrete::<Image>()?;
        ...
    }
    _ => ...,
}
