pub trait Encode {
// Required method
fn encode<E: Encoder>(&self, encoder: &mut E) -> Result<(), EncodeError>;
}Expand description
Any source that can be encoded. This trait should be implemented for all types that you want to be able to use with any of the encode_with methods.
This trait will be automatically implemented if you enable the derive feature and add #[derive(bincode::Encode)] to your trait.
Implementing this trait manually
If you want to implement this trait for your type, the easiest way is to add a #[derive(bincode::Encode)], build and check your target/generated/bincode/ folder. This should generate a <Struct name>_Encode.rs file.
For this struct:
struct Entity {
pub x: f32,
pub y: f32,
}It will look something like:
impl bincode::Encode for Entity {
fn encode<E: bincode::enc::Encoder>(
&self,
encoder: &mut E,
) -> core::result::Result<(), bincode::error::EncodeError> {
bincode::Encode::encode(&self.x, encoder)?;
bincode::Encode::encode(&self.y, encoder)?;
Ok(())
}
}From here you can add/remove fields, or add custom logic.
