Enum secret_cosmwasm_std::SystemError

#[non_exhaustive]
pub enum SystemError {
    InvalidRequest {
        error: String,
        request: Binary,
    },
    InvalidResponse {
        error: String,
        response: Binary,

    ExceededRecursionLimit {},
}

SystemError is used for errors inside the VM and is API friendly (i.e. serializable).

This is used on return values for Querier as a nested result: Result<StdResult, SystemError> The first wrap (SystemError) will trigger if the contract address doesn’t exist, the QueryRequest is malformated, etc. The second wrap will be an error message from the contract itself.

Such errors are only created by the VM. The error type is defined in the standard library, to ensure the contract understands the error format without creating a dependency on cosmwasm-vm.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
