borsh-schema-writer

This library provides a function to take a Struct with the BorshSchema trait and writes the schema to a specified file. This file can then be hosted in a registry, file system, database, web storage, etc... for consumers to use. Here is an example:

use std::fs::File;
use std::io::BufReader;
use borsh::{BorshDeserialize, BorshSerialize, BorshSchema};
use borsh::schema::{BorshSchemaContainer, Definition, Fields};
use borsh_schema_writer::schema_writer::write_schema;

#[derive(Debug, Default, BorshSerialize, BorshDeserialize, BorshSchema)]
pub struct Person {
    first_name: String,
    last_name: String
}

fn write_schema_example() {
write_schema(Person::default(), "./tests/schema/person_schema.dat".to_string());
    let file = File::open("./tests/schema/person_schema.dat").unwrap();
    let mut reader = BufReader::new(file);
    let container_from_file = BorshSchemaContainer::deserialize_reader(&mut reader).expect("Deserialization for BorshSchemaContainer failed");
}
