Struct Shell 

pub struct Shell<'tree, L, IO, H, C>
where
    L: AccessLevel,
    IO: CharIo,
    H: CommandHandler<C>,
    C: ShellConfig,
{ /* private fields */ }

Shell orchestration struct.

Brings together all components following the unified architecture pattern. Uses single code path for both auth-enabled and auth-disabled modes.

Implementations

impl<'tree, L, IO, H, C> Shell<'tree, L, IO, H, C>

where L: AccessLevel, IO: CharIo, H: CommandHandler<C>, C: ShellConfig,

pub fn new(tree: &'tree Directory<L>, handler: H, io: IO) -> Self

Create new Shell

Starts in Inactive state. Call activate() to show welcome message and prompt.

impl<'tree, L, IO, H, C> Shell<'tree, L, IO, H, C>

where L: AccessLevel, IO: CharIo, H: CommandHandler<C>, C: ShellConfig,

pub fn activate(&mut self) -> Result<(), IO::Error>

Activate the shell (show welcome message and initial prompt).

Transitions from Inactive to appropriate state (LoggedOut or LoggedIn).

pub fn deactivate(&mut self)

Deactivate shell (transition to Inactive). Clears session and resets to root directory.

pub fn process_char(&mut self, c: char) -> Result<(), IO::Error>

Process single character of input (main entry point for char-by-char processing).

pub fn poll(&mut self) -> Result<(), IO::Error>

Poll for incoming characters and process them. For interrupt-driven/DMA/async/RTOS use process_char() directly.

pub fn io(&self) -> &IO

Get reference to I/O interface (for inspection or direct control).

pub fn io_mut(&mut self) -> &mut IO

Get mutable reference to I/O interface (for manipulation or direct control).

Trait Implementations

impl<'tree, L, IO, H, C> Debug for Shell<'tree, L, IO, H, C>

where L: AccessLevel, IO: CharIo, H: CommandHandler<C>, C: ShellConfig,

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
