Trait darling::FromDeriveInput

pub trait FromDeriveInput {
    pub fn from_derive_input(input: &DeriveInput) -> Result<Self, Error>;
}

Creates an instance by parsing an entire proc-macro derive input, including the, identity, generics, and visibility of the type.

This trait should either be derived or manually implemented by a type in the proc macro crate which is directly using darling. It is unlikely that these implementations will be reusable across crates.

Required methods

pub fn from_derive_input(input: &DeriveInput) -> Result<Self, Error>

Create an instance from syn::DeriveInput, or return an error.
