Enum HostKeyPolicy 

pub enum HostKeyPolicy {
    Strict {
        known_hosts_path: Option<String>,
    },
    AcceptNew,
    Insecure,
}

How the server’s host key is verified during the SSH handshake.

Defaults to AcceptNew. The insecure, verification-off mode is a distinct explicit variant so it can never be selected by accident.

Variants

Strict

Reject any host key that is not already recorded in known_hosts. The most secure policy; requires the key to be pre-provisioned.

Fields

known_hosts_path: Option<String>

Path to the known_hosts file. None uses the standard ~/.ssh/known_hosts location.

AcceptNew

Trust-on-first-use: accept and record a host key the first time it is seen (in ~/.ssh/known_hosts), but reject a key that has changed from a previously recorded one. This is the default.

Insecure

Disable host-key verification entirely. Insecure — vulnerable to man-in-the-middle attacks. Use only against trusted networks / test servers.

impl JsonSchema for HostKeyPolicy

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema
