Struct DeviceHandler 

pub struct DeviceHandler {
    pub dyn_param: HashMap<String, String>,
    /* private fields */
}

Fields

dyn_param: HashMap<String, String>

Dynamic parameters for input substitution (e.g., passwords, system names)

Implementations

impl DeviceHandler

pub fn is_equivalent(&self, other: &DeviceHandler) -> bool

Checks if two DeviceHandlers are equivalent (used for connection parameter comparison).

pub fn new(config: DeviceHandlerConfig) -> Result<DeviceHandler, ConnectError>

Creates a new DeviceHandler from a declarative configuration snapshot.

impl DeviceHandler

pub fn from_config(config: &DeviceHandlerConfig) -> Result<Self, ConnectError>

Build a handler from a public configuration snapshot.

impl DeviceHandler

pub fn diagnose_state_machine(&self) -> StateMachineDiagnostics

Analyze the state transition graph for common template issues.

impl DeviceHandler

pub fn read(&mut self, line: &str)

Reads a line of output and updates the current state.

pub fn read_prompt(&mut self, line: &str) -> bool

Checks if a line matches a prompt pattern.

pub fn read_sys_prompt(&mut self, line: &str) -> bool

Checks if a line matches a system-specific prompt pattern.

pub fn read_need_write(&mut self, line: &str) -> Option<(String, bool)>

Checks if a line requires input and returns the input to send.

pub fn current_state(&self) -> &str

Returns the current state name.

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

Returns the currently captured system name, if available.

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

Returns last prompt text matched by the state machine.

pub fn states(&self) -> Vec<String>

Returns all declared state names.

pub fn edges(&self) -> Vec<(String, String, String, bool, bool)>

Returns all configured transition edges.

pub fn error(&self) -> bool

Checks if the current state is an error state.

impl DeviceHandler

pub fn trans_state_write( &self, state: &str, sys: Option<&String>, ) -> Result<Vec<(String, String)>, ConnectError>

Calculates the commands needed to transition to a target state.
