Enum HttpPolicyError 

pub enum HttpPolicyError {
    NotAllowed,
    NoEgress,
    Transport(FnError),
    Status(u16),
}

Why a capability-gated HTTP call was refused.

The loaders share the decisions and keep their own encoding: the Extism loader maps these onto the numeric FnError codes its guest ABI pins (0xC20, 0xC21, 0xC23), the Rhai loader onto EvalAltResult strings. Splitting it this way is what lets both share the policy without either changing its published error contract.

Variants

NotAllowed

The URL is outside the granted Capability::Network allow-list.

NoEgress

No HttpEgress implementation was wired in.

Transport(FnError)

The transport itself failed.

Status(u16)

The response carried a >= 400 status.
