Enum JumpHostConfig 

pub enum JumpHostConfig {
    SshConfigHostRef {
        ssh_config_host: String,
    },
    Detailed {
        host: String,
        user: Option<String>,
        port: Option<u16>,
        ssh_key: Option<String>,
    },
    Simple(String),
}

Jump host configuration format.

Supports multiple formats:

• Legacy string format: "[user@]hostname[:port]"
• SSH config reference: "@alias" (references ~/.ssh/config Host alias)
• Structured format with optional ssh_key
• Structured SSH config reference with ssh_config_host field

Uses #[serde(untagged)] to allow seamless deserialization of all formats.

Variants

SshConfigHostRef

Structured SSH config reference format with ssh_config_host field Must be listed first for serde to try matching object format before string

Fields

ssh_config_host: String

SSH config Host alias to reference (from ~/.ssh/config)

Detailed

Structured format with optional ssh_key field

Fields

host: String

user: Option<String>

port: Option<u16>

ssh_key: Option<String>

Simple(String)

Legacy string format: “[user@]hostname[:port]” Also supports SSH config reference with “@” prefix: “@alias”

Implementations

impl JumpHostConfig

pub fn to_connection_string(&self) -> String

Convert to a connection string for resolution.

Note: For SSH config references (@alias or ssh_config_host), this returns the alias name with “@” prefix. The actual resolution to hostname/user/port must be done by the caller using SSH config parsing.

pub fn ssh_key(&self) -> Option<&str>

Get the SSH key path if specified

pub fn is_ssh_config_ref(&self) -> bool

Check if this is an SSH config reference (either @alias string or ssh_config_host field)

pub fn ssh_config_host(&self) -> Option<&str>

Get the SSH config host alias if this is an SSH config reference.

Returns the alias name (without “@” prefix) for:

• JumpHostConfig::Simple("@alias") -> Some(“alias”)
• JumpHostConfig::SshConfigHostRef { ssh_config_host: "alias" } -> Some(“alias”)
• Other variants -> None
