Struct SubdomainResolver 

pub struct SubdomainResolver { /* private fields */ }

Resolves tenant from the Host header subdomain.

Extracts the leftmost subdomain segment by stripping the rightmost base_domain_parts segments. For example, with base_domain_parts = 2:

• acme.yourapp.com → slug "acme"
• yourapp.com → None (no subdomain)
• acme.yourapp.com:8080 → slug "acme" (port stripped)

Example

use ferro_rs::tenant::{SubdomainResolver, DbTenantLookup};
use std::sync::Arc;

let resolver = SubdomainResolver::new(2, Arc::new(lookup));

Implementations

impl SubdomainResolver

pub fn new( base_domain_parts: usize, tenant_lookup: Arc<dyn TenantLookup>, ) -> Self

Create a new SubdomainResolver.

• base_domain_parts — number of base domain segments to strip (e.g. 2 for yourapp.com)
• tenant_lookup — lookup implementation for DB verification
