        _context: CommandSuggestionContext<'_>,
        _suggestions: &mut CommandSuggestions<'_, '_>,
    ) { ... }
}

Typed, deterministically keyed parser contract for extension arguments.

Required Associated Types

type Value: DowncastType + Debug + Send + Sync + 'static

Concrete keyed value retained in the parsed command context.

Required Methods

fn parse( &self, reader: &mut CommandReader<'_, '_>, source: CommandParserSource<'_>, ) -> Result<Self::Value, CommandError>

Parses one value from the reader’s current cursor.

fn protocol_argument( &self, ) -> (ProtocolArgumentType, Option<ProtocolSuggestionType>)

Returns the vanilla command-tree parser and optional server suggestion provider.

Provided Methods

fn list_suggestions( &self, _context: CommandSuggestionContext<'_>, _suggestions: &mut CommandSuggestions<'_, '_>, )

Adds context-aware completions for a partially entered value.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
