Module completion 

Command-mode and argument completion content + menu rendering.

State and lifecycle live in tau_cli_term_raw; this module supplies the content (which candidates exist for a given buffer) and the presentation (how the menu block is laid out and styled).

Public types:

• CommandCompletion — command completion entry
• CompletionItem / CompletionData — dynamic argument completions
• build_candidates — turns the current buffer into a Vec<Candidate>
• render_menu_block — turns a CompletionView into a StyledBlock

Structs

CommandCompletion

One command-mode completion entry with its display description.

CommandName

One command-mode token, including its leading : (for example, ":model").

CompletionData

Thread-safe storage for dynamic command and argument completions.

CompletionItem

A single argument completion candidate.

CompletionRule

A single prompt completion rule keyed by the word prefix that activates it.

CompletionRules

Prompt completion rules. If multiple rules match, the longest prefix wins.

Enums

CompletionRuleKind

Named completion behavior selected by prompt completion config.

Functions

build_candidates

Builds the candidate list for the given buffer/cursor.

build_candidates_with_rules

Builds candidates using explicit prompt completion rules.

render_menu_block

Renders the completion menu as a StyledBlock: each candidate on its own line, with the selected entry highlighted.

Type Aliases

ArgCompleter

Closure that produces argument completions for a command, given the already-typed args (the last element is the partial arg being completed; may be empty for “just typed a space”).
