Trait Fold 

pub trait Fold {
    // Required method
    fn apply(&mut self, record: &LogRecord);
}

A pure accumulator over log records. apply performs no I/O and asks no clock; unknown record kinds must be ignored (additive schema growth — doc 13 §4).

Required Methods

fn apply(&mut self, record: &LogRecord)

Fold one record into the accumulator.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".

Implementations on Foreign Types
