Struct FilterDefinition

pub struct FilterDefinition { /* private fields */ }

The main filter definition

This is the main handle for Txn Filter definition, and this can be used to serialize and deserialize filters from JSON.

Examples

let filter_json_str = r#"{"txnFilter":{"NullaryTRUE":{}}}"#;

let tf = serde_json::from_str::<FilterDefinition>(filter_json_str)?;

match tf.txn_filter {
     TxnFilter::NullaryTRUE(_) => (),
     _ => panic!(),
}

assert_eq!(serde_json::to_string(&tf)?, filter_json_str);

Implementations

impl FilterDefinition

pub fn from_json_str(filt_str: &str) -> Result<FilterDefinition, Box<dyn Error>>

Generate filter from JSON String

Examples

let filter_json_str = r#"{"txnFilter":{"NullaryTRUE":{}}}"#;

let tf = FilterDefinition::from_json_str(filter_json_str)?;

match tf.txn_filter {
     TxnFilter::NullaryTRUE(_) => (),
     _ => panic!(),
}

pub fn is_armored(filt: &str) -> bool

Test if filter string is ascii armored

pub fn from_armor( filt_armor_str: &str, ) -> Result<FilterDefinition, Box<dyn Error>>

Generate filter from ascii armor JSON String

Examples

let filter_ascii_armor = "base64:eyJ0eG5GaWx0ZXIiOnsiTnVsbGFyeVRSVUUiOnt9fX0K";

let tf = FilterDefinition::from_armor(filter_ascii_armor)?;

match tf.txn_filter {
     TxnFilter::NullaryTRUE(_) => (),
     _ => panic!(),
}
