Struct MigrateError

pub struct MigrateError { /* private fields */ }

A generic wrapper when TryFrom::Error is raised on Migration

Acts somewhat like anyhow::Error, to store TryFrom::Error-s as your structs try to migrate. Works with anything that implements std::error::Error.

use magic_migrate::{MigrateError, TryMigrate};


impl magic_migrate::TryMigrate for PersonV2 {
    type TryFrom = PersonV1;
    type Error = MigrateError;

    fn deserializer<'de>(input: &str) -> impl serde::de::Deserializer<'de> {
        toml::Deserializer::new(input)
    }
}

let result: Result<PersonV2, MigrateError> = PersonV2::try_from_str_migrations("name = 'Richard'").unwrap();
