[−][src]Trait libhoney::FieldHolder

pub trait FieldHolder {
    fn add(&mut self, data: HashMap<String, Value>);

    fn add_field(&mut self, name: &str, value: Value);

    fn add_func<F>(&mut self, func: F)
    where
        F: Fn() -> Result<(String, Value)>;
}

FieldHolder implements common functions that operate on the fields component of a struct (usually Event or Builder). This avoids some duplication of code.

Required methods

fn add(&mut self, data: HashMap<String, Value>)

add data to the current (event/builder) fields

fn add_field(&mut self, name: &str, value: Value)

add_field adds a field to the current (event/builder) fields

fn add_func<F>(&mut self, func: F) where
    F: Fn() -> Result<(String, Value)>, 

add_func iterates over the results from func (until Err) and adds the results to the event/builder fields
