Trait fadroma::scrt::permit::Permission

source · 
pub trait Permission: Serialize + JsonSchema + Clone + PartialEq { }
Expand description

Marker trait that enables strongly typed permits with a finite permission set. Any type that implements Serialize + JsonSchema + Clone + PartialEq already implements this trait due to its blanket implementation.

Examples

use fadroma::{
    scrt::permit::{Permit, PermitParams},
    serde::{Serialize, Deserialize},
    schemars::{self, JsonSchema}
};
 
#[derive(Serialize, JsonSchema, Clone, PartialEq)]
enum MyPermissions {
    A,
    B
}
 
let params = PermitParams::new("allowed_contract").permissions([MyPermissions::A]);
// This constructor is available in test code only, not with cfg(target_arch = "wasm32")!
let permit = Permit::new("from", params);
 
assert!(permit.has_permission(&MyPermissions::A));
assert!(!permit.has_permission(&MyPermissions::B));
