Trait Implementations

impl<'a, T: Clone> Clone for Task<'a, T>

fn clone(&self) -> Task<'a, T>

Returns a copy of the value.

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

Performs copy-assignment from source.

Performs the conversion from an owned Self to [Cid].

impl<T> DagJson for Task<'_, T>

where T: From<Ipld> + Clone, Ipld: From<T>,

fn to_json(&self) -> Result<Vec<u8>, Error<Unit>>

Serialize Self type to JSON bytes.

fn to_json_string(&self) -> Result<String, Error<Unit>>

Serialize Self type to JSON String.

fn from_json(data: &[u8]) -> Result<Self, Error<Unit>>

Deserialize Self type from JSON bytes.

fn from_json_string(json: String) -> Result<Self, Error<Unit>>

Deserialize Self type from JSON String.

fn to_file(&self, filename: String) -> Result<(), Error<Unit>>

Write JSON to file.

impl<'a, T: Debug> Debug for Task<'a, T>

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

Formats the value using the given formatter.

impl<'de, 'a, T> Deserialize<'de> for Task<'a, T>

where T: Deserialize<'de>,

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T> From<Task<'_, T>> for Ipld

where Ipld: From<T>,

fn from(task: Task<'_, T>) -> Self

Converts to this type from the input type.

impl<'a, T> From<Task<'a, T>> for Invocation<'a, T>

where Ipld: From<T>,

fn from(task: Task<'a, T>) -> Self

Converts to this type from the input type.

impl<'a, T: PartialEq> PartialEq for Task<'a, T>

fn eq(&self, other: &Task<'a, T>) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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