Trait MeshResolver 

Source 
pub trait MeshResolver {
    // Required method
    fn resolve(
        &self,
        ident: &MeshIdent,
        kind: MeshLookup,
    ) -> Result<String, MeshError>;
}
Expand description

Resolve crate::EnvValue::FromMesh references to literal env values.

Defined in workload-spec so clients (agents, desktop, CLI) can render specs against fake mesh state without depending on the yubaba crate. Yubaba’s production implementation (in yubaba::deploy::mesh_resolve) reads from raft state.

Resolution rules match the arch doc §“Mesh-derived env”:

  • MeshLookup::Url — "http://<ident>:<port>", where port is the first entry in the referenced workload’s MeshExpose.ports.
  • MeshLookup::Host — the bare DNS-ish identifier as authored (e.g. "noisetable-db.pdx").
  • MeshLookup::Port — the first port stringified, e.g. "5432".

Implementations should perform the port lookup atomically — a Url and Port resolved in the same deploy must agree on which port was first.

Required Methods§

fn resolve( &self, ident: &MeshIdent, kind: MeshLookup, ) -> Result<String, MeshError>

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
