The contribution API. Every observed CC tool gets one Capturer impl in this crate’s source tree.

Required Methods

fn name(&self) -> &'static str

Stable identifier; matches [capture.<name>] in config and the filter UI label.

fn tool_name(&self) -> &'static str

CC tool name to match (e.g. "Bash", "Read").

fn render_pre(&self, ctx: &HookContext, input: &Value) -> Option<DisplayEntry>

Render a PreToolUse event. Return None to suppress (e.g. for noisy calls).

Provided Methods

fn subscribes_to(&self) -> &'static [HookEvent]

Which hook events this capturer wants. Default: both Pre and Post.

fn pre_rewrite(&self, _ctx: &HookContext, _input: &Value) -> RewriteDecision

Optional rewrite. Default: passthrough. Only the Bash capturer overrides this in v0.1.

fn render_post( &self, _ctx: &HookContext, _input: &Value, _response: &Value, ) -> Option<DisplayEntryUpdate>

Render a PostToolUse event. Default: no update (Pre-only capturers). The wrapper correlates Pre↔Post by tool_use_id and applies this update.

Dyn Compatibility

This trait is dyn compatible.

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