Trait Encode 

pub trait Encode {
    // Required method
    fn encode(&self, buf: &mut Vec<u8>);

    // Provided method
    fn stringify(&self) -> String { ... }
}

Encode Trait

This trait is used for formatting a field’s value. Encoding support has already been added for all scalar types and many standard collections. If you wish to format your own type, just implement this trait.

pub struct CustomStruct {
    pub key1: i32,
    pub key2: bool,
    pub key3: String,
}

impl logkit::Encode for CustomStruct {
    #[inline]
    fn encode(&self, buf: &mut Vec<u8>) {
        // format your struct into buf
        unimplemented!()
    }
}

The Encode Trait

Required Methods

fn encode(&self, buf: &mut Vec<u8>)

Encode object to bytes and append it to buf

Provided Methods

fn stringify(&self) -> String

Encode object to string

Dyn Compatibility

This trait is dyn compatible.

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