Struct MirrorArgs

pub struct MirrorArgs {
    pub mirror: String,
    pub replay: String,
}

Convenience cli arguments for setting up a transport with an optional mirror or replay file.

The mirror argument will write the stdin to the file. The replay argument will read the file as input.

Example

The example below shows the typical usage of the MirrorArgs struct. It records an LSP or DAP session and replays it to compare the output.

If the language server has stable output, the replayed output should be the same.

$ my-lsp --mirror /tmp/mirror.log > responses.txt
$ ls /tmp
mirror.log
$ my-lsp --replay /tmp/mirror.log > responses-replayed.txt
$ diff responses.txt responses-replayed.txt

Fields

mirror: String

Mirror the stdin to the file

replay: String

Replay input from the file

Trait Implementations

impl Args for MirrorArgs

fn group_id() -> Option<Id>

Report the [ArgGroup::id][crate::ArgGroup::id] for this set of arguments

fn augment_args<'b>(__clap_app: Command) -> Command

Append to [Command] so it can instantiate Self via [FromArgMatches::from_arg_matches_mut]

fn augment_args_for_update<'b>(__clap_app: Command) -> Command

Append to [Command] so it can instantiate self via [FromArgMatches::update_from_arg_matches_mut]

impl Clone for MirrorArgs

fn clone(&self) -> MirrorArgs

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl CommandFactory for MirrorArgs

fn command<'b>() -> Command

Build a [Command] that can instantiate Self.

fn command_for_update<'b>() -> Command
