Expand description
Options for constructing a Ghci
. This is like a lower-effort builder interface, mostly provided
because Rust tragically lacks named arguments.
Some of the other *Opts
structs include borrowed data from the Opts
struct, but this one
is fully owned; ultimately, this is because Ghci
is run through a ShutdownHandle
, which
requires that the task is fully owned.
Fields§
§command: ClonableCommand
The command used to start the underlying ghci
session.
error_path: Option<Utf8PathBuf>
A path to write ghci
errors to.
enable_eval: bool
Enable running eval commands in files.
hooks: HookOpts
Lifecycle hooks, mostly ghci
commands to run at certain points.
restart_globs: GlobMatcher
Restart the ghci
session when paths matching these globs are changed.
reload_globs: GlobMatcher
Reload the ghci
session when paths matching these globs are changed.
no_interrupt_reloads: bool
Determines whether we should interrupt a reload in progress or not.
stdout_writer: GhciWriter
Where to write what ghci
emits to stdout
. Inherits parent’s stdout
by default.
stderr_writer: GhciWriter
Where to write what ghci
emits to stderr
. Inherits parent’s stderr
by default.
clear: bool
Whether to clear the screen before reloads and restarts.
Implementations§
source§impl GhciOpts
impl GhciOpts
sourcepub fn from_cli(opts: &Opts) -> Result<(Self, Option<DuplexStream>)>
pub fn from_cli(opts: &Opts) -> Result<(Self, Option<DuplexStream>)>
Construct options for Ghci
from parsed command-line interface arguments as Opts
.
This extracts the bits of an Opts
struct relevant to the Ghci
session without
cloning or taking ownership of the entire thing.
If running in TUI mode, ghci
output (from stdout_writer
and stderr_writer
) is sent to
the stream given by the second return value.
