Trait LocalHandler 

pub trait LocalHandler {
    type Output: Serialize;

    // Required method
    fn handle(
        &mut self,
        matches: &ArgMatches,
        ctx: &CommandContext,
    ) -> HandlerResult<Self::Output>;
}

Trait for local (single-threaded) command handlers.

Unlike Handler, this trait:

• Does NOT require Send + Sync
• Takes &mut self instead of &self
• Allows handlers to mutate their internal state directly

Required Associated Types

type Output: Serialize

The output type produced by this handler (must be serializable)

Required Methods

fn handle( &mut self, matches: &ArgMatches, ctx: &CommandContext, ) -> HandlerResult<Self::Output>

Execute the handler with the given matches and context.

Implementors

impl<F, T> LocalHandler for LocalFnHandler<F, T>

where F: FnMut(&ArgMatches, &CommandContext) -> HandlerResult<T>, T: Serialize,

type Output = T
