Struct ContextChain 

pub(crate) struct ContextChain<S, R = BrigadierRuntime>
where
    R: CommandRuntime<S>,
{
    contexts: Arc<[Arc<CommandContext<S, R>>]>,
    position: usize,
}

A flattened sequence of redirect contexts followed by one executable context.

Fields

contexts: Arc<[Arc<CommandContext<S, R>>]>

position: usize

Implementations

impl<S, R> ContextChain<S, R>

where R: CommandRuntime<S>,

pub(super) fn try_flatten(root: Arc<CommandContext<S, R>>) -> Option<Self>

pub(crate) fn stage(&self) -> ContextChainStage

Returns the kind of work represented by the current stage.

pub(crate) fn top_context(&self) -> &CommandContext<S, R>

Returns the parsed context at the current stage.

pub(crate) fn next_stage(&self) -> Option<Self>

Advances to the next redirect or executable stage.

impl<S> ContextChain<S, BrigadierRuntime>

pub(crate) fn run_modifier( &self, source: Arc<S>, consumer: &dyn Fn(&CommandContext<S, BrigadierRuntime>, bool, i32), forked: bool, ) -> Result<Vec<Arc<S>>, CommandSyntaxError>

Applies the current stage’s source modifier.

pub(crate) fn run_executable( &self, source: Arc<S>, consumer: &dyn Fn(&CommandContext<S, BrigadierRuntime>, bool, i32), forked: bool, ) -> Result<i32, CommandSyntaxError>

Runs the current stage’s terminal command.

pub(crate) fn execute_all( &self, source: S, consumer: &dyn Fn(&CommandContext<S, BrigadierRuntime>, bool, i32), ) -> Result<i32, CommandSyntaxError>

Executes the complete chain with Brigadier’s synchronous semantics.

Trait Implementations

impl<S, R> Clone for ContextChain<S, R>

where R: CommandRuntime<S>,

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.
