pub trait Encode {
// Required method
fn encode<W>(&self, writer: &mut W) -> Result<(), Error>
where W: FeltWriter;
}Expand description
Any type that can be serialized into a series of Felts. This trait corresponds to the
serialize function of the Cairo Serde trait.
This trait can be derived as long as all the fields in type implement Encode.
§Example
This example demonstrates deriving the trait and then using it to serialize an instance into
Vec<Felt>.
use starknet_core::codec::Encode;
#[derive(Encode)]
struct CairoType {
a: u32,
b: Option<bool>,
}
let instance = CairoType {
a: 3,
b: Some(true),
};
let mut serialized = vec![];
instance.encode(&mut serialized);
assert_eq!(vec![Felt::THREE, Felt::ZERO, Felt::ONE], serialized);Required Methods§
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
