Derive Macro DeriveValidate 

#[derive(DeriveValidate)]
{
    // Attributes available to this derive:
    #[validate]
    #[sensitive]
}

Derive the Validate trait for a struct.

This macro generates an implementation of premortem::Validate that validates all fields according to their #[validate(...)] attributes.

The generated code uses stillwater’s Validation::all() to run all validations in parallel and accumulate ALL errors, not just the first one.

Example

use premortem::Validate;

#[derive(Validate)]
struct DatabaseConfig {
    #[validate(non_empty, message = "Host is required")]
    host: String,

    #[validate(range(1..=65535))]
    port: u16,

    #[validate(positive)]
    pool_size: u32,

    #[validate(nested)]
    tls: Option<TlsConfig>,
}
