TxResult.log is missing type information

[0xForerunner]

TxResult is defined as such:

/// Transaction result.
#[derive(Serialize, Deserialize, Debug, Clone, PartialEq, Eq)]
pub struct TxResult {
    pub log: Option<String>,
    pub gas_wanted: Option<String>,
    pub gas_used: Option<String>,
    pub events: Vec<abci::Event>,
}

The log field is defined as a string here, but I believe it's correct type should look something like this:

#[derive(Debug, Clone, Serialize, Deserialize)]
struct Log {
    events: Vec<SubEvent>,
}

#[derive(Debug, Clone, Serialize, Deserialize)]
struct SubEvent {
    attributes: Vec<Attribute>,
    #[serde(rename = "type")]
    type_string: String,
}

#[derive(Debug, Clone, Serialize, Deserialize)]
struct Attribute {
    key: String,
    value: String,
}
