Struct DryRunShell 

pub struct DryRunShell {
    pub config: ShellConfig,
}

Dry-run shell: logs what would be executed and returns fake success. Probe methods (command_exists, command_output) delegate to real implementations because they are read-only and safe to call.

Fields

config: ShellConfig

Shell execution configuration (e.g. overlay viewport height).

Trait Implementations

impl Default for DryRunShell

fn default() -> DryRunShell

Returns the “default value” for a type.

impl Shell for DryRunShell

fn run_command( &self, _label: &str, program: &str, args: &[&str], output: &mut dyn Output, _mode: OutputMode, ) -> Result<CommandResult, ShellError>

Run program with args, displaying progress under label.

fn shell_exec( &self, script: &str, output: &mut dyn Output, _mode: OutputMode, ) -> Result<CommandResult, ShellError>

Run an arbitrary shell script string (passed to bash -c / powershell -Command).

fn command_exists(&self, program: &str) -> bool

Return true when program can be found on PATH.

fn command_output( &self, program: &str, args: &[&str], ) -> Result<String, ShellError>

Run program args and return its captured stdout as a trimmed String.

fn exec_capture( &self, cmd: &str, output: &mut dyn Output, _mode: OutputMode, ) -> Result<CommandResult, ShellError>

Run a shell command, capturing stdout/stderr silently without display. In dry-run mode (DryRunShell), logs the command and returns success without executing.

fn exec_interactive( &self, cmd: &str, output: &mut dyn Output, _mode: OutputMode, ) -> Result<(), ShellError>

Run a shell command with inherited stdio (for interactive flows like aws sso login). In dry-run mode (DryRunShell), logs the command and returns success without executing.
