Struct soroban_env_common::EnvVal

pub struct EnvVal<E: Env, V> {
    pub env: E,
    pub val: V,
}

Some type of value coupled to a specific instance of Env, which some of the value’s methods may call into to support some conversion and comparison functions.

The value and Env instance used in an EnvVal will vary by context:

• In contract code compiled for WASM, the Env is a zero-sized Guest struct
• In contract code compiled natively for local testing, the Env is a reference-counted Host
• Inside the Host, the Env is either a Host or a weak reference to a Host

The value will typically either be RawVal or one of its tag-specific wrapper types.

Fields

env: E

The environment to call into for comparison and conversion assistance.

val: V

The value that will call into the environment as needed.
