Type Alias CompletionFunc 

pub type CompletionFunc = Box<dyn Fn(&Context, &str) -> Result<CompletionResult> + Send + Sync>;

Type alias for completion functions

Completion functions are called when the user presses TAB to get suggestions. They receive the current context and the partial text being completed.

Arguments

• &Context - The current command context with flags and arguments
• &str - The partial text being completed

Returns

Returns a Result<CompletionResult> with the suggested completions

Examples

use flag_rs::completion::{CompletionFunc, CompletionResult};
use flag_rs::context::Context;
use flag_rs::error::Result;

// A completion function that suggests file names
let file_completer: CompletionFunc = Box::new(|_ctx, partial| {
    Ok(CompletionResult::new()
        .add("file1.txt")
        .add("file2.txt")
        .add("file3.log"))
});

// A dynamic completion function that uses context
let pod_completer: CompletionFunc = Box::new(|ctx, partial| {
    // In a real implementation, this would query the Kubernetes API
    let namespace = ctx.flag("namespace")
        .map(|s| s.as_str())
        .unwrap_or("default");
    Ok(CompletionResult::new()
        .add_with_description("pod-abc-123", format!("Pod in namespace {}", namespace))
        .add_with_description("pod-def-456", format!("Pod in namespace {}", namespace)))
});
