Struct PrecompileRegistry 

pub struct PrecompileRegistry { /* private fields */ }

Installed set of precompiles for deferred-node validation and evaluation.

Routing is entirely id-based. The empty registry is valid but rejects every precompile-owned tag, which is useful for programs that do not use precompile-backed deferred nodes.

Implementations

impl PrecompileRegistry

pub const fn new() -> PrecompileRegistry

Creates an empty precompile registry.

pub fn is_empty(&self) -> bool

Returns whether this registry contains no installed precompiles.

pub fn with_precompile<P>(self, precompile: P) -> PrecompileRegistry

where P: Precompile + 'static,

Adds a precompile to the registry and returns self for chaining.

Panics on setup errors: id drift, a framework-reserved id, or a duplicate id.

pub fn merge(&mut self, registry: PrecompileRegistry) -> &mut PrecompileRegistry

Merges another registry into this one.

Panics on duplicate ids, preserving Self::with_precompile’s setup-failure behavior.

pub fn decode_precompile_tag( &self, tag: Tag, ) -> Result<NodeType, PrecompileError>

Decodes a precompile-owned tag by routing its local arguments to the owning precompile.

Unknown ids are registry failures; recognized ids whose arguments are invalid are attributed to the owning precompile. Framework tags are handled by the internal framework-aware decoder and rejected here. NodeType::True is reserved for the framework TRUE sentinel, so a precompile that returns it is rejected as an invalid node.

Trait Implementations

impl Clone for PrecompileRegistry

fn clone(&self) -> PrecompileRegistry

Performs copy-assignment from source.

impl Debug for PrecompileRegistry

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for PrecompileRegistry

fn default() -> PrecompileRegistry

Returns the “default value” for a type.
