Struct GrammarContributions 

pub struct GrammarContributions { /* private fields */ }

The per-plugin accumulator the grammar::Host impl records into during register-grammar (lib.rs). Held in PluginState; drained by the host after the registration export returns (PH7.7c). The record_* methods are the sync host-func bodies (they only push — they cannot trap), factored here (the host_services::walk_within_grant precedent) so the recording logic is unit-testable without a PluginState / guest.

Implementations

impl GrammarContributions

pub fn record_motion( &mut self, name: String, doc: String, spec: WitMotionSpec, callback: u32, )

Record a motion contribution (the grammar.register-motion body).

pub fn record_operator( &mut self, name: String, doc: String, spec: WitOperatorSpec, callback: u32, )

Record an operator contribution (grammar.register-operator).

pub fn record_text_object( &mut self, name: String, doc: String, spec: WitTextObjectSpec, callback: u32, )

Record a text-object contribution (grammar.register-text-object).

pub fn record_action( &mut self, name: String, doc: String, spec: WitActionSpec, callback: u32, )

Record an action contribution (grammar.register-action).

pub fn record_ex_command( &mut self, name: String, doc: String, spec: WitExCommandSpec, parse_callback: u32, apply_callback: u32, )

Record an ex-command contribution (grammar.register-ex-command). Carries two callbacks — parse-ex-args + apply-ex-command.

pub fn len(&self) -> usize

How many contributions were recorded.

pub fn is_empty(&self) -> bool

True when the plugin registered no grammar (the degenerate case).

pub fn take(&mut self) -> Vec<RecordedContribution>

Drain the recorded contributions, leaving the accumulator empty. Called by the host after register-grammar returns (PH7.7c) to build native specs.

Trait Implementations

impl Default for GrammarContributions

fn default() -> GrammarContributions

Returns the “default value” for a type.
