Trait FromParams

pub trait FromParams:
    Sealed
    + Send

    + 'static {
    // Required method
    fn from_params(params: Option<Value>) -> Result<Self>;
}

A trait implemented by all JSON-RPC method parameters.

Required Methods

fn from_params(params: Option<Value>) -> Result<Self>

Attempts to deserialize Self from the params value extracted from Request.

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.
