Struct Capability

pub struct Capability {
    pub issuer: Address,
    pub params: Json,
}

Fields

issuer: Address

params: Json

Implementations

impl Capability

Capability is defined in the wit bindings, but constructors and methods here. A Capability is a combination of an Address and a set of Params (a serialized JSON string by convention). Capabilities are attached to messages to either share that capability with the receiving process, or to prove that a process has authority to perform a certain action.

pub fn new<T, U>(address: T, params: U) -> Capability

where T: Into<Address>, U: Into<String>,

Create a new Capability. Takes an Address and a parameter, which is a JSON string.

pub fn issuer(&self) -> &Address

Read the node ID from a Capability.

pub fn params(&self) -> &str

Read the params from a Capability.

pub fn params_json(&self) -> Result<Value, Error>

Read the params from a Capability as a serde_json::Value.

pub fn set_params_json(&mut self, value: Value) -> Result<(), Error>

Set the params for a Capability from a serde_json::Value.

Trait Implementations

impl Clone for Capability

fn clone(&self) -> Capability

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Capability

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

Formats the value using the given formatter.

impl<'a> Deserialize<'a> for Capability

fn deserialize<D>(deserializer: D) -> Result<Capability, D::Error>

where D: Deserializer<'a>,

Deserialize this value from the given Serde deserializer.

impl Display for Capability

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

Formats the value using the given formatter.

impl From<&Capability> for Capability

fn from(input: &Capability) -> Self

Converts to this type from the input type.

impl<T, U> From<(T, U)> for Capability

where T: Into<Address>, U: Into<String>,

fn from(input: (T, U)) -> Self

Converts to this type from the input type.

impl Hash for Capability

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Capability

fn eq(&self, other: &Self) -> 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 Capability

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
